THREE:The next novelist who appeared was of a very different school. Richardson was an elaborate anatomist of character; Fielding and Smollett were master painters of life and manners, and threw in strong dashes of wit and humour; but they had little sentiment. In Laurence Sterne (b. 1713; d. 1768) came forth a sentimentalist, who, whilst he melted his readers by touches of pathos, could[174] scarcely conceal from them that he was laughing at them in his sleeve. The mixture of feeling, wit, double entendre, and humour of the most subtle and refined kind, and that in a clergyman, produced the oddest, and yet the most vivid, impressions on the reader. The effect was surprise, pleasure, wonder, and no little misgiving; but the novelty and charm of this original style were so great that they carried all before them, but not without the most violent censures from the press on his indecencies, especially considering his position as a clergyman. Sterne was the grandson of that Richard Sterne, a native of Mansfield, in Nottinghamshire, who was chaplain to Archbishop Laud, and attended him on the scaffold. Laurence Sterne was the son of a lieutenant in the army, and was born at Clonmel, in Ireland, his grandfather having then become Archbishop of York. Sterne, therefore, on taking orders, was on the way of preferment, and received the rectory of Stillington and the perpetual curacy of Coxwold, both in Yorkshire. There he wrote not only sermons, but satire, particularly his "History of a Watchcoat." But it was his novel of "Tristram Shandy" which brought him into sudden popularity. After this, his "Sentimental Journey" completed his reputation; and his Maria and her lamb, his uncle Toby, Corporal Trim, Yorick, Doctor Slop, the widow Wadman, and his lesser characters, usurped for a long period the tears and laughter of the nation.

THREE:On the 28th of March the Ministry, as completed, was announced in the House, and the writs for the re-elections having been issued, the House adjourned for the Easter holidays, and on the 8th of April met for business. The first affairs which engaged the attention of the new Administration were those of Ireland. We have already seen that, in 1778, the Irish, encouraged by the events in North America, and by Lord North's conciliatory proposals to Congress, appealed to the British Government for the removal of unjust restrictions from themselves, and how free trade was granted them in 1780. These concessions were received in Ireland with testimonies of loud approbation and professions of loyalty; but they only encouraged the patriot party to fresh demands. These were for the repeal of the two obnoxious Acts which conferred the legislative supremacy regarding Irish affairs on England. These Acts werefirst, Poynings' Act, so called from Sir Edward Poynings, and passed in the reign of Henry VII., which gave to the English Privy Council the right to see, alter, or suppress any Bill before the Irish Parliament, money Bills excepted; the second was an Act of George I., which asserted in the strongest terms the right of the king, Lords, and Commons of England to legislate for Ireland.

THREE:On the 15th of April Buonaparte quitted Paris, for the last time as a permanent abode; on the 16th he was at Mainz, and on the 25th at Erfurt. Before quitting Paris he had appointed Maria Louisa regent in his absence. This he deemed a stroke of policy likely to conciliate the Emperor of Austria. But the Empress's power was merely nominal. She could appear at the Council board, but it was only as the instrument of the Emperor; he carried all active power along with him, and ruled France from his camp. He had still upwards of fifty thousand troops in the garrisons of Prussia, commanded by Eugene, the Viceroy of Italy; and he advanced at the head of three hundred thousand men. Eugene Beauharnais had been compelled necessarily to evacuate Dantzic, Berlin, and Dresden as the Russians and Prussians advanced, and to retreat upon the Elbe. In the month of May Bernadotte, according to concert, crossed over to Stralsund with thirty-five thousand men, and awaited the reinforcements of Russians and Germans which were to raise his division to eighty thousand men, with which he was to co-operate with the Allies, and protect Hamburg. The Allies, under Tetterborn, Czernicheff, and Winzengerode, spread along both sides of the Elbe, the Germans rising enthusiastically wherever they came. Hamburg, Lübeck, and other towns threw open their gates to them. The French general, Morand, endeavouring to quell the rising of the people of Lüneburg, was surprised by the Russians, and his detachment of four thousand men was cut to pieces, or taken prisoners. Eugene marched from Magdeburg to surprise Berlin, but was met at M?ckern, defeated, and driven back to Magdeburg. Such was the success of the Allies, and the exulting support of the people, that even Denmark and Saxony began to contemplate going over to the Allies. Blucher entered Dresden on the 27th of March, driving Davoust before him, who blew up an arch of the fine bridge to cover his retreat. The Emperor of Russia and King of Prussia entered the city soon afterwards, and were received by the inhabitants with acclamations. On the 28th of April died the old Russian general, Kutusoff, at Bautzen, and was succeeded by General Wittgenstein.

FORE:The preparations for invasion turned the attention of the British Government to ports where it was supposed the troops would be embarked. Ostend was regarded with particular suspicion, and Sir Home Popham was sent in May with a small squadron, conveying a thousand men, under Colonel Coote, to destroy the ships and sluices of the Bruges canal there. The troops were landed, and did their work, but found themselves unable to regain the ships from the violence of the wind and the surf, and were surrounded and compelled to surrender. In the autumn of this year Admiral Duckworth sailed for Minorca, and landed eight hundred men, under Sir Charles Stuart, who readily made themselves masters of the island.工場建設、プラント新設の計画の立案には、大きな労力を要します。当社では、お客様の一助となるべく、官庁届け出の助成を行いながら、工場建設を進め、抱えておられる問題の解決に取り組んでおります。

FORE:William IV. then sent for the veteran Grey, who formed a Ministry with unusual ease, chiefly of the Whig and Canningite elements. His chief difficulty was how to dispose of the volatile Brougham. The king had no objection to accept him as one of the Ministers, and Brougham himself wished to be Master of the Rolls, assuming that Sir John Leech was to become Lord Chancellor of Ireland, with a peerage, and that Mr. Plunket was to be Lord Chancellor of England. To this arrangement, however, the king and Lord Grey peremptorily objected. Brougham was then offered the Attorney-Generalship, which he calmly refused, upon which Lord Grey declared that his hopes of being able to form an Administration were at an end, and he waited on his Majesty for the purpose of communicating to him the failure of his negotiations. "Why so?" inquired the king. "Why not make him Chancellor? Have you thought of that?" The answer was, "No; your Majesty's objection to the one appointment seemed to preclude the other." "Not at all, not at all," replied the king; and the reasons for one appointment and against the other were very clearly stated by his Majesty, namely, that Brougham as Master of the Rolls and member for Yorkshire would be far too powerful. Mr. Brougham was left in the dark for some time about the intentions of Lord Grey, for on the 17th of November he said he had nothing to do with the Administration, except in the respect he bore them, and as a member of the House. On the 19th he presented petitions, and spoke on them in the Commons, without intimating any change of position. Hence it may easily be supposed that he surprised the world, as well as his friends, by suddenly appearing on November the 22nd in the House of Lords as Lord Chancellor of England. This was certainly a high office to which he was elevated, and for which the exigencies of party made him necessary; but, in accepting it, he sacrificed a great position which seemed to gratify all the desires of intellectual ambition; and, in order to induce his compliance, Lord Grey was obliged to appeal to his generous sympathies, his public spirit, and his devotion to his party. Lord Brougham and Vaux became, said a wag, "Vaux et praeterea nihil."主要機器等の仕様を決定し、プラントの基本フローや配置を決定します。

FORE:It was proposed also to form, in certain districts, relief committees, which should be empowered to receive subscriptions, levy rates, and take charge of donations from the Government; and that out of the fund thus raised they should establish soup kitchens, and deliver rations to the famishing inhabitants. Sir John Burgoyne, Inspector-General of Fortifications, was appointed to superintend the works. Lord John Russell referred to measures for draining and reclaiming waste land in Ireland, and to advances of money for this purpose to the proprietors, to be repaid in instalments spread over a number of years. On a subsequent day, in answer to questions from Mr. Roebuck, the noble lord gave a statement of the sums that had already been advanced. 2,000,000 had been issued on account of the Poor Employment Act of the last Session. He expected that not less than 500,000 or 600,000 a month would be spent from the present time until August, and he calculated the whole expenditure would not be less than 7,000,000. There was great difference of opinion on the subject of the Government plans. A counter-scheme for the establishment of reproductive works deserves to be noticed for the interest it excited and the attention it occupied for years afterwardsnamely, the railway plan of Lord George Bentinck. Acts of Parliament, he said, had been passed for 1,582 miles of railway in Ireland, of which only 123 miles had then been completed, while 2,600 miles had been completed in England. In order to encourage the formation of Irish railways, therefore, he proposed that for every 100 expended by the companies 200 should be lent by the Government at the same interest at which they borrowed the money, Mr. Hudson, who was "chairman of 1,700 miles of railroad," pledging his credit that the Government would not lose a shilling by the transaction. By adopting this plan they could give reproductive employment to 109,000 men in different parts of the country, for earth-works, fences, drains, and watercourses connected with the lines. This would give support of 550,000 souls on useful work, tend to develop the resources of the country, and produce such improvement that the railways constructed would add 23,000,000 to the value of landed property in twenty-five years, and would pay 22,500 a year to the poor rates. The purchase of land for the railways would moreover place 1,250,000 in the hands of Irish proprietors, for the employment of fresh labour, and 240,000 in the hands of the occupying tenants for their own purposes. The Government also would reap from the expenditure of 24,000,000 on railways in Ireland, an enormous increase of revenue in the augmented consumption of articles of excise and customs. The noble lord's speech, which lasted two hours and a half, was received with cheers from both sides of the House. Leave was given to bring in the Bill, though it was strongly objected to by Lord John Russell, Mr. Labouchere, and other members of the Government. It was also opposed by Sir Robert Peel, who exposed the unsoundness of the economic principles involved in it. The Bill was rejected by a majority of 204, the numbers being 118 for the second reading, and 322 against it. Notwithstanding this decision, loans were subsequently advanced to certain Irish railways, amounting to 620,000, so that the objection of the Government was more to the extent than to the principle of Lord George Bentinck's measure.詳細設計に基づきポンプや部品類の購入品の調達先を選定し、発注します。

FORE:Here all further progress became impossible. The Spaniards having reduced their debt to less than one half the original sum, were fighting stoutly to reduce it to nothing. There appeared no chance but for arms to decide it. Cardinal Fleury, with his usual pacific disposition, made an effort to avert the war by guaranteeing to undertake the payment of the ninety-five thousand pounds by Spain, provided that the British fleet was withdrawn from the Mediterranean. But English spirit, even in Walpole, had now reached its limit of patience. The king and the nation were equally in a mood for war. Walpole, therefore, ceased to listen any longer to the Spanish objections, but took his stand on the true British ground of resistance to the right of search, and on that of an acknowledgment of all British rights and claims in North America. Instead of withdrawing the Mediterranean fleet, he ordered its reinforcement, sent Sir Chaloner Ogle with fresh ships to the West Indies, and Sir John Norris was ordered to put to sea with a third squadron. The above demands being peremptorily made from the Court of Madrid, and being rejected, war was proclaimed in London on the 19th of October. Walpole, who had reluctantly resorted to this master evil, as he heard the rejoicings, exclaimed, "They may ring the bells now, but they will soon be wringing their hands!" The first symptoms of the consequences which the war was likely to produce were seen in the new hopes which it awoke in the ranks of the Jacobites. Large numbers of them met at Edinburgh, and drew up a bond of association, pledging one another to take arms and venture life and fortune for the restoration of the Stuart. On the other hand, those nations on which England calculated for aid hung back and remained neutral. The Dutch were bound to furnish certain troops in case of war, and, before the declaration of it, Horace Walpole was despatched by his brother to demand their production; but they pleaded the menaces of France, which threatened them with invasion by fifty thousand men if they assisted the English, and which held out to them the prospect of their obtaining that trade to the Spanish colonies which England had enjoyed. As for France herself, she assumed an air rather ominous of war than of peace, and thus Britain was left alone in the contest.The crossing of the Beresina, in the circumstances, was a desperate design, but there was no alternative but surrender. Tchitchagoff was posted with his army on the opposite or left bank; Wittgenstein and Platoff were pressing down to join them; and Kutusoff, with the grand army of Russia, was in the rear, able, if he could have been induced to do it, to drive Buonaparte and his twelve thousand men into the Beresina, and destroy them. After reconnoitring the river Napoleon determined to deceive Tchitchagoff by a feint at passing at Borissov, but really to make the attempt at Studienka, above Borissov. He therefore kept up a show of preparations to cross at Borissov, but got ready two bridges at Studienka, one for the artillery and baggage, the other for the troops and miscellaneous multitude. At this juncture he was joined by Victor and Oudinot with their fifty thousand men well provided with everything. Thus he was now possessed of sixty-two thousand men besides stragglers; and his design of deceiving Tchitchagoff succeeding so completely that the latter withdrew his whole force from opposite to Studienka and concentrated it at Borissov, he began on the 26th of November to cross the river, and had a strong force already over before Tchitchagoff discovered his error and came back to attack him. So far all went so well that Buonaparte again boasted of his star.安全を第一に、管理技術者が責任を持って施工、工程、品質の管理を行いながら協力会社と連携し進めていきます。

FORE:Very strong hopes were entertained by the Liberal party from the Administration of Lord Wellesley, but it was his misfortune to be obliged to commence it with coercive measures, always the ready resource of the Irish Government. The new Viceroy would have removed, if possible, the causes of public disturbance; but, in the meantime, the peace must be preserved and sanguinary outrages must be repressed, and he did not shrink from the discharge of his duty in this respect on account of the popular odium which it was sure to bring upon his Government. Mr. Plunket, as Attorney-General, was as firm in the administration of justice as Mr. Saurin, his high Tory predecessor, could be. The measures of repression adopted by the legislature were certainly not wanting in severity. The disorders were agrarian, arising out of insecurity of land tenure, rack rents, and tithes levied by proctors upon tillage, and falling chiefly upon the Roman Catholic population, who disowned the ministrations of the Established Church. The remedies which the Government provided for disturbances thus originating were the Suspension of the Habeas Corpus Act and the renewal of the Insurrection Act. By the provisions of the latter the Lord-Lieutenant was empowered, on the representation of justices in session that a district was disturbed, to proclaim it in a state of insurrection, to interdict the inhabitants from leaving their homes between sunset and sunrise, and to subject them to visits by night, to ascertain their presence in their own dwellings. If absent, they were considered idle and disorderly, and liable to transportation for seven years! These measures encountered considerable opposition, but they were rapidly passed through both Houses, and received the Royal Assent a week after Parliament met. Under these Acts a number of Whiteboys and other offenders were tried and convicted, several hanged, and many transported. Lord Wellesley must have felt his position very disagreeable between the two excited parties. To be impartial and just was to incur the hostility of both. Possibly he became disgusted with the factions that surrounded him. Whether from this cause, or from an indolent temper, or from the feeling that he was hampered and restrained, and could not do for the country what he felt that its well-being required, or from ill health, it is certain that he became very inactive. A member of the Cabinet writes about him thus:"I find the Orange party are loud in their abuse of Lord Wellesley, for shutting himself up at the Ph?nix Park, lying in bed all day, seeing nobody, and only communicating with Secretary Gregory by letter. Indeed, I believe that the latter is more than he often favours Secretaries Peel and Goulburn with." In another letter, the same Minister, Mr. Wynn, complains of his total neglect of his correspondence with England. This, he said, was inexcusable, because those on whom the chief responsibility rested had a right to know his views upon the state of Ireland, in order to be able to meet the Opposition during the sitting of Parliament. This was written towards the end of April, and at that time the Government had not for a month heard a syllable from him on the agitated questions of tithes, magistracy, and police. The state of Ireland, indeed, became every day more perplexing and alarming. A revolutionary spirit was abroad, and all other social evils were aggravated by famine, which prevailed in extensive districts in the south and west. The potato crop, always precarious, was then almost a total failure in many counties, and left the dense population, whose existence depended upon it, totally destitute. The cry of distress reached England, and was responded to in the most generous spirit. Half a million[223] sterling was voted by Parliament, and placed at the disposal of Lord Wellesley, to be dispensed in charitable relief and expended on public works for the employment of the poor. In addition to this, the English people contributed from their private resources the sum of three hundred thousand pounds for the relief of Irish distress. On the 30th of May there was a ball given for the same object, in the King's Theatre, London, which produced three thousand five hundred pounds.プラント完成後、性能が出るか試運転を行って確認、調整を行います。

FORE:Of all the expectants of office in the Wellington Administration, the most bitterly disappointed was the ex-Chancellor, Lord Eldon, to whom official life had from long habit become almost a necessity. He had enjoyed power long enough in reason to admit of his retirement with a contented mind; but the passion for it was never stronger than at the present moment. He hastened to London a few days after Christmas on account of rumours of a dissolution of the Cabinet. Having so often done this when there was a talk of a Ministerial crisis, he was called the "stormy petrel." Believing that he had mainly contributed to bring about the Ministerial catastrophe, he was dreadfully mortified when he saw in the newspapers the list of the new Ministers beginning thus: "Chancellor, Lord Lyndhurst." He had not set his heart this time on the office of Lord Chancellor, he would have been content with the Presidentship of the Council or Privy Seal; but his name was not found in the list at all, nor had he been consulted in any way, or informed about what was going forward during the fortnight that passed before the Ministerial arrangements were completed. This utter neglect of his claims excited his anger and indignation to the utmost, and caused him to indulge in bitter revilings and threats against the new Cabinet. The great Tory lords shared in his resentment, and felt that they were all insulted in his person. Referring to the Ministerial arrangements, he wrote:"You will observe, Dudley, Huskisson, Grant, Palmerston, and Lyndhurst (five) were all Canningites, with whom the rest were three weeks ago in most violent contest and opposition; these things are to me quite marvellous. How they are all to deal with each other's conduct, as to the late treaty with Turkey and the Navarino battle, is impossible to conjecture. As the first-fruits of this arrangement, the Corporation of London have agreed to petition Parliament to repeal the laws which affect Dissenters."We now arrive at the "Irish Crisis," the famine of 1846 and 1847one of the greatest calamities that ever afflicted the human race. In order to understand fully the events connected with this visitation, it is necessary to notice the social condition of the country which rendered its effects so destructive. Ireland had long been in a chronic state of misery, which has been ascribed by the most competent judges to the peculiar state of the land tenure in that country. It had often been predicted by writers on the state of Ireland, that, owing to this rottenness at the foundation of the social fabric, it would come down with a crash some day. The facts reported by the Census Commissioners of 1841 showed that this consummation could not be far off. Out of a population of 8,000,000, there were 3,700,000 above the age of five years who could neither read nor write; while nearly three millions and a half lived in mud cabins, badly thatched with straw, having each but one room, and often without either a window or a chimney. These figures indicate a mass of ignorance and poverty which could not be contemplated without alarm, and the subject was, therefore, constantly pressed upon the attention of Parliament. As usual in cases of difficulty, the Government, feeling that something should be done, and not knowing what to do, appointed, in 1845, a commission to inquire into the relations between landlord and tenant, and the condition of the working classes. At the head of this commission was the Earl of Devon, a benevolent nobleman, whose sympathies were on the side of the people. Captain Kennedy, the secretary to the Commissioners, published a digest of the report of the evidence, which presented the facts in a readable form, and was the means of diffusing a large amount of authentic information on the state of Ireland. The Commissioners travelled through the country, held courts of inquiry, and examined witnesses of all classes. As the result of their extensive intercourse with the farming classes and their own observations, they were enabled to state that in almost every part of Ireland unequivocal symptoms of improvement, in spite of many embarrassing and counteracting circumstances, continually presented themselves to the view, and that there existed a very general and increasing spirit and desire for the promotion of such improvement, from which the most beneficial results might fairly be expected. Indeed, speaking of the country generally, they add: "With some exceptions, which are unfortunately too notorious, we believe that at no former period did so active a spirit of improvement prevail; nor could well-directed measures for the attainment of that object have been proposed with a better prospect of success than at the present moment."プラント、機器の安全と安定稼働のために、定期的なメンテナンスをお薦めいたします。
