"Accompany you. Presently, but not quite in the way you imagine. I have made my confession in a way that Mr. Lawrence thoroughly appreciates. It was I who murdered Leon Lalage, my husband, in this house; it was I who palmed those notes off on Dr. Bruce. No reason to tell you why now. And it was I in this very house who robbed my late mistress of her jewels and forged the letter from her husband that caused her to take poison. After that I have no more to say. Gentlemen, I am much obliged by your kind attention, and I say farewell to you, thus."
"It shall be done," he said hoarsely. "Speak."In speaking of the mechanical knowledge to be gained, and of the privileges afforded for learners in engineering-works in a general way, it must, of course, be assumed that such works afford full facilities for learning some branch of work by the best practice and in the most thorough manner. Such establishments are, however, graded from the highest class, on the best branches of work, where a premium would be equitable, down [23] to the lowest class, performing only inferior branches of work, where there can be little if any advantage gained by serving an apprenticeship.One of the problems connected with the handling of material is to determine where hand-power should stop and motive-power beginwhat conditions will justify the erection of cranes, hoists, or tramways, and what conditions will not. Frequent mistakes are made in the application of power when it is not required, especially for handling material; the too common tendency of the present day being to apply power to every purpose where it is possible, without estimating the actual saving that, may be effected. A common impression is that motive power, wherever applied to supplant hand labour in handling material, produces a gain; but in many cases the [66] fallacy of this will be apparent, when all the conditions are taken into account.
