FORE:"I expect you'll get orders from five or six addresses," said Prout. "If so, send the stuff on, not too much at a time, and ask for references. You'll get the reference, of course; in other words, Jones and Company, of Gray's Inn, will recommend Smith and Company, of Market Street. When you get all the references in let me know, because by that means I shall be in possession of every address used by these fellows."

FORE:"Not? Oh! they are sure to do it. All the villages are burning already. The smoke suffocates us here. In Bressoux there is not a house left standing, and in other villages all civilians have been killed, men, women, and children. Not even the tiniest babies escaped.... Oh!... and now it is Li��ge's turn!"

FORE:Another wide-spread superstition was the belief in prophetic or premonitory dreams. This was shared by some even among those who rejected supernatural religion,��a phenomenon not unparalleled at the present day. Thus the228 elder Pliny tells us how a soldier of the Praetorian Guard in Rome was cured of hydrophobia by a remedy revealed in a dream to his mother in Spain, and communicated by her to him. The letter describing it was written without any knowledge of his mishap, and arrived just in time to save his life.348 And Pliny was himself induced by a dream to undertake the history of the Roman campaigns in Germany.349 Religious believers naturally put at least equal confidence in what they imagined to be revelations of the divine will. Galen, the great physician, often allowed himself to be guided by dreams in the treatment of his patients, and had every reason to congratulate himself on the result. The younger Pliny, Suetonius, Dion Cassius, and the emperors Augustus and Marcus Aurelius, were all influenced in a similar manner; and among these Dion, who stands last in point of time, shows by his repeated allusions to the subject that superstition, so far from diminishing, was continually on the increase.350Machine-drawing may in some respects be said to bear the same relation to mechanics that writing does to literature; persons may copy manuscript, or write from dictation, of what they do not understand; or a mechanical draughtsman may make drawings of a machine he does not understand; but neither such writing or drawing can have any value beyond that of ordinary labour. It is both necessary and expected that a draughtsman shall understand all the various processes of machine construction, and be familiar with the best examples that are furnished by modern practice.

FORE:Attention has already been called to the fact that Epicurus, although himself indifferent to physical science, was obliged, by the demands of the age, to give it a place, and a very large place, in his philosophy. Now it was to this very side of Epicureanism that the fresh intellect of Rome most eagerly attached itself. It is a great mistake to suppose that the Romans, or rather the ancient Italians, were indifferent to speculations about the nature of things. No one has given more eloquent expression to the enthusiasm excited by such enquiries than Virgil. Seneca devoted a volume to physical questions, and regretted that worldly distractions should prevent them from being studied with the assiduity they deserved. The elder Pliny lost his life in observing the eruption of Vesuvius. It was probably the imperial despotism, with its repeated persecutions of the ��Mathematicians,�� which alone prevented Italy from entering on the great scientific career for which she was predestined in after ages. At any rate, a spirit of active curiosity was displaying itself during the last days of the republic, and we are told that nearly all the Roman Epicureans applied themselves particularly to the physical side of their master��s doctrine.202 Most of all was Lucretius distinguished by a veritable passion for science, which haunted him even in his dreams.203 Hence, while Epicurus regarded the knowledge of Nature simply as a means for overthrowing religion, with his disciple the speculative interest seems to precede every other consideration, and religion is only introduced afterwards as an obstacle to be removed from the enquirer��s path. How far his natural genius might have carried the poet in this direction, had he fallen into better hands, we cannot tell. As it was, the gift of what seemed a complete and infallible interpretation of physical phenomena relieved him from the necessity of independent investigation, and induced him to accept the most preposterous conclusions as demonstrated truths. But we can see how105 he is drawn by an elective affinity to that early Greek thought whence Epicurus derived whatever was of any real value in his philosophy.At once he saw Larry��s amazed, relieved expression and followed the older comrade��s eyes.
