THREE:"A very singular circumstance, is it not?" he asked, quietly.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.
FORE: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.

FORE:For the rest of the journey I used my only remaining means of transport, my legs, and after a walk of some hours got to the frontier of The Netherlands near Oud-Vroenhoven. A Netherland custom-house officer asked for my papers, and I showed him my huge passport. The man looked at the sheet critically, and made out that I could not possibly be a Netherlander, as I was the holder of a "foreign" passport.The story flashed like lightning from one end of London to the other. Leona Lalage had been an important personage. Her face was familiar to the society paper window; no report of a great function was complete without a description of her dress. She was a constant source of "copy" to the paragraphists; her dinners and her parties were things to imitate and envy. And now the crash had come.

THREE:He bought one eagerly enough, and stood spellbound on the pavement whilst he read. It was all here, even down to a signed copy of the confession. Lawrence had seen to that. Bruce turned into his club in a dazed kind of way. The smoking-room was full, he was the centre of a group, all of which seemed eager to shake hands. It was all so sudden that Bruce was not himself yet.
FORE:To master the various details of machine manufacture, including draughting, founding, forging, and fitting, is of itself a work equal to most professional pursuits, to say nothing of manual skill; and when we come to add machine functions and their application, generating and transmitting power, with other things that will necessarily be included in practice, the task assumes proportions that makes it appear a hopeless one. Besides, the work of keeping progress with the mechanic arts calls for a continual accretion of knowledge; and it is no small labour to keep informed of the continual changes and improvements that are going on in all parts of the world, which may at any time modify and change both machines and processes. But few men, even under the most favourable conditions, have been able to qualify themselves as competent mechanical engineers sooner than at forty years of age.
