FORE:In regard to shaded elevations, it may be said that photography has superseded them for the purpose of illustrating completed machines, and but few establishments care to incur the expense of ink-shaded elevations. Shaded elevations cannot be made with various degrees of care, and in a longer or shorter time; there is but one standard for them, and that is that such drawings should be made with great care and skill. Imperfect shaded elevations, although they may surprise and please the unskilled, are execrable in the eyes of a draughtsman or an engineer; and as the making of shaded elevations can be of but little assistance to an apprentice draughtsman, it is better to save the time that must be spent in order to make such drawings, and apply the same study and time to other matters of greater importance.

FORE:In working to regular scales, such as one-half, one-eighth, or one-sixteenth size, a good plan is to use a common rule, instead of a graduated scale. There is nothing more convenient for a mechanical draughtsman than to be able to readily resolve dimensions into various scales, and the use of a common rule for fractional scales trains the mind, so that computations come naturally, and after a time almost without effort. A plain T square, with a parallel blade fastened on the side of the head, [80] but not imbedded into it, is the best; in this way set squares can pass over the head of a T square in working at the edges of the drawing. It is strange that a draughting square should ever have been made in any other manner than this, and still more strange, that people will use squares that do not allow the set squares to pass over the heads and come near to the edge of the board.

FORE:The cause which first arrested and finally destroyed the free movement of Greek thought was not any intrinsic limitation or corruption of the Greek genius, but the ever-increasing preponderance of two interests, both tending, although in different ways and different degrees, to strengthen the principle of authority and to enfeeble the principle of reason. One was the theological interest, the other was the scholastic interest. The former was the more conspicuous and the more mischievous of the two. From the persecution of Anaxagoras to the prohibition of philosophical teaching by Justinian, we may trace the rise and spread of a reaction towards superstition, sometimes advancing and sometimes receding, but, on the whole, gaining ground from age to age, until from the noontide splendour of Pericles we pass to that long night which stretches in almost impenetrable darkness down to the red and stormy daybreak of the Crusades. And it was a reaction which extended through all classes, including the philosophers themselves. It seems to me that where the Athenian school, from Socrates on, fall short of their predecessors, as in some points they unquestionably do, their inferiority is largely due to this cause. Its influence is very perceptible in weakening the speculative energies of thosexii who stand at the greatest distance from the popular beliefs. It was because dislike for theology occupied so large a place in the thoughts of Epicurus and his disciples, that they valued science only as a refutation of its teaching, instead of regarding it simply as an obstacle to be removed from the path of enquiry. More than this; they became infected with the spirit of that against which they fought, and their absolute indifference to truth was the shadow which it cast on their minds.

FORE:Those wide carts had passed us now, and we could proceed slowly. The bridge led to a farmhouse with tall trees and underwood. They took me to the right, to a densely overgrown spot, where a clearing had been made amidst some smaller shrubs. In the centre stood a table covered with a shining white cloth, and a goodly number of wine-bottles and glasses. Half a dozen officers in fine uniforms, gilt collars and epaulettes, were seated around it.
