In Mr Wesley’s article on “Dialling,” there is the following beautiful sentence: “Time is the greatest treasure in this world that a mortal can be intrusted with. We are not only probationers for eternity by the help of time, but even the little interests of this world are managed by the means of it. To divide time by dials, clocks, and watches, is a faint imitation of God Almighty, who has divided the year into spring, summer, autumn, and winter, and even our life into days and nights.” Of _Geometry_ he writes: “All our most necessary as well as most noble arts and sciences depend on it. None of the mechanical arts can ever be brought to perfection without it; and if painters were ignorant of proportion, angles, circles, and squares, all their works would want beauty, and themselves would want satisfaction. A joiner cannot so much as cut a round table unless he understands a circle; nor a carpenter square a piece of timber unless he know, by the rule of square figures, when his work is finished. The watch and clock makers would be at a loss, if it were not for this science; and no builder could regularly design a fabric without a knowledge of geometrical problems. Navigation and gunnery can never be understood without geometry; and to these I may add, fortification, dialling, music, astronomy, and surveying. It would be needless to say any more of the advantages of geometry, here being enough to fire the mind of any ingenious student to a diligent inquiry into it.” Writing on _Optics_, he says: “’Tis pleasant to undeceive the eye in the common accidents of life, and to see it approach, in some measure, towards that certainty of judging and apprehending _visibles_ that it will attain to at the day of resurrection, when it will be above the power of being cheated by concave or convex, or deluded by a refraction or reflection. This may, in a great measure, be accomplished in this world by such as give themselves up to the study of optics.” There are other articles on painting, astronomy, and navigation, and glances at geography, music, architecture, grammar, and rhetoric. The general “Essay on all Sorts of Learning” concludes thus: “Whoever makes a trial of the worth of learning will find that all encomiums come far short of the thing itself; and that those only can best reflect upon its value who are sensible of the enjoyment of it.” Such, then, is a general outline of the contents of “The Young Student’s Library,” published in 1692; but no one can form an adequate idea of the work without seeing it. None but immense readers and careful writers like Samuel Wesley and his Athenian friends could have put such a book together.
