THREE:It may be useless or even wrong to institute invidious comparisons between different callings which are all useful and necessary, and the matter is not introduced here with any view of exalting the engineering profession; it is for some reasons regretted that the subject is alluded to at all, but there is too much to be gained by an apprentice having a pride and love for his calling to pass over the matter of its dignity as a pursuit without calling attention to it. The gauntlet has been thrown down and comparison provoked by the unfair and unreasonable place that the politician, the metaphysician, and the moral philosopher have in the past assigned to the sciences and constructive arts. Poetry, metaphysics, mythology, war, and superstition have in their time engrossed the literature of the world, and formed the subject of what was alone considered education.

THREE:A remarkable strike had taken place in the Leo XIII Hospital. The head of this institution, Dr. Tits, also had been taken as a hostage. It was the most blackguardly act one can think of, to take away the man who had spent night and day mostly nursing wounded Germans. Dr. Noyons found it so harsh that he took counsel with the other doctors, and they decided not to resume work before Dr. Tits came back. This of course happened immediately.

THREE:The curious one shrugged his shoulders. Then a loud clear voice rang to the roof, the voice of a woman who declared that she could prove it. A ripple of amazement followed. Before it died away Hetty became conscious of the fact that the voice was hers, and that she had spoken.In the flowerbeds in front of the station many corpses had been buried, especially those of soldiers who had been killed in the fight near Louvain. The station itself was well guarded, but, thanks to my passport and resolute manner, I gained admission and was finally ushered into the presence of the man who is responsible for the destruction of Louvain, Von Manteuffel.

THREE:In constructing patterns where it is optional whether to employ cores or not, and in preparing drawings for castings which may have either a ribbed or a cored section, it is nearly always best to employ cores. The usual estimate of the difference between the cost of moulding rib and cored sections, as well as of skeleton and cored patterns, is wrong. The expense of cores is often balanced by the advantage of having an 'open mould,' that is accessible for repairs or facing, and by the greater durability and convenience of the solid patterns. Taking, for example, a column, or box frame for machinery, that might be made either with a rib or a cored section, it would at first thought seem that patterns for a cored casting would cost much more by reason of the core-boxes; but it must be remembered that in most patterns labour is the principal expense, and what is lost in the extra lumber required for a core-box or in making a solid pattern is in many cases more than represented in the greater amount of labour required to construct a rib pattern.
