Book Description
Excerpt from Prentice-Hall Tax Service for 1919 This allowance is not based upon the difference between the actual war cost of such facilities and what they would have cost at pre-war prices. Obviously the taxpayer is not entitled to recover or extinguish through amortization more than the difference between the war cost of such property and what he can sell the property for after the war, or if he continues to need and use it in his business, what it would have cost him after the war. As the rule is expressed in Article 183 of the Regulations: The total amount to be extinguished by amortization, in general, is the excess of the unextinguished or unrecovered cost of the property over its maximum value (either for sale or for use as part of the plant or equipment of a going business) under stable post war.

Excerpt from The Perfected American Watch Splendid investment. It gives better return and depreciates less in proportion than any other article of personal wear or use. Like the human heart, it works unremittingly. If treated with common care and cleaned as occasion requires, it will, excepting accidents, outlive its wearer. Though the case be thinner at the end of twenty years than it was when new, the movement, if originally good, will be as vigorous and exact as the day it left the factory. Moreover, it never goes out of vogue. How much is an overcoat that cost you forty dol lars worth after five years' wear, com pared with a watch that cost the same We are speaking now about the waltham watch, and to the person who is not carrying one. Eleven mil lion people have them. To such the watches have told their own story. Fifty years ago all watches were made in Eu ro p e, chiefly in Switzerland.

Excerpt from On Some Antiquities in the Neighbourhood of Dunecht House Aberdeenshire It was known to the archaeologist that there were ogam inscriptions in the district, two Of them being among the most important in Caledonia; and that within an easy motor drive there was a minuscule inscription of six lines Of which no satisfactory explanation had been given. This inscription they had visited in a previous year. Further, the quick eye Of the hostess of Dunecht had caught sight of some curious sculptures on a stone by the road-side on the way to the minus cule inscription; and other like stones in the neighbourhood had been shewn in Stuart's two volumes of Sculptural Stones of Scotland. The suggestion was then made that for the sake of visitors at Dunecht a sort Of guide book should be prepared, giving some simple description of the several Objects and their meaning and uses.

Book Description
Excerpt from Treatise on Clock and Watch Making: Theoretical and Practical My not having complied with the wish of the late la meated Professor Robison of this city, may perhaps be received as an apology for the absence of those theoretical and philosophical discussions which might otherwise have formed a prominent feature in the Work now submitted to the public. That learned gentleman, so early as 1793, had projected a work on the theory and practice of Horology, * a subject which he had studied with particular attention; and, in a letter addressed to me, re quested my assistance and participation in the compo tion and publication of the proposed work. The active duties of an extensive business forbade my acceptance of so very attering and apparently profitable proposi tion: I'have, however, endeavoured, to the best of my abilities, to supply the want of such a publication, unac companied indeed with those spirited and scientific views of Mechanical Philosophy, which it would have derived from the aid of Professor Robison, yet, I atter myself, not the less calculated for the practical Clock and Watch maker, nor for the student and amateur in those branches of minute mechanism, - the wonderful results of which are every day unfolding themselves to the world.

Book Description
Excerpt from Rules and Practice for Adjusting Watches In the early days of horology the apprentice was taught the art of making a complete watch. Production was slow, very few duplicate watches were constructed, and it was necessary that extra material be made individually by hand in the same way that the original part was produced. As time passed the value of the repairer was indicated by his ability to make new parts and to replace them so that the watch would again be in running condition. This was the prevailing situation for many years and the repairer was judged according to his skill in making and finishing the various parts. A similar method of judging ability is still in force among some employers, although the development of the industry into machine and specialized work has made many changes in regard to the most important duties of the repairer. It is no longer necessary for him to know how to make a complete watch and only on occasional instances is it necessary for him to make a part. Genuine material for modern watches is supplied by the manufacturer at less expense than it can be produced by the individual and in this particular branch of the work the repairers requirements have been very considerably curtailed. A more exacting and a higher standard of timekeeping has developed, however, and in this field the requirements of the watchmaker have increased to the extent that it is no longer sufficient to merely restore a good watch to running condition. It must keep time. This development has grown gradually and surely and the past twenty-five years may be assumed as the period of greatest advance. It has been made possible by scientific and practical refinements which permit the adjustment of watches so that they will keep time within closely defined allowances under varying conditions.
