Book Description
Excerpt from The Breeding of Fur Animals The usefulness Of breeding data 111 this situation may be illustrated by the case of the marten (fig. At its experiment station near Saratoga Springs, N. Y., established in 1923, the Bureau has been studying the breeding and the gestation period of the marten. As a result it has found that a period Of 9% months elapses between the time of copulation and birth. With so long a period Of gestation, many pregnant females are bound to be destroyed under the prevailing system of open and close seasons. It is obvious that unless the trapping season for a fur animal corresponds accurately with its gestation-free period, the close season will not accomplish what it is intended to: the prospective generation will be destroyed along with the one trapped. Even this precaution, however, would be ineffective in the case of the marten or the fisher, for their gestation periods are too long. A 5 or 10-year closed period is necessary to prevent local or even general extermination Of these two fur animals.

Excerpt from Breeding Mink for Their Fur Of all the small fur-bearing animals in this section, the mink is the most valuable, bringing as much as $8 for prime, dark mink, and there is reason to believe that within the next two years the price will advance to $12 or more. For breeding purposes they were bringing $25 each, as reported by Mr. W. C. Gates of Idaho, in March, 19] 3.

Book Description
Excerpt from The Fur Traders and Fur Bearing Animals The author has not attempted to write a new his tory of any part of the Animal Kingdom, but to present in condensed form and simple language authentic information regarding the structural formation, external appearance and distinguishing features of the more important fur-bearing animals; and to show by comprehensive charts and tables the proper grouping, and the relations and affinities each to each, of the different species. Attention has also been given to Fur Farming, and the commercial value of the different skins; the quantities of each used annually by furriers in pursuit of their calling;the processes and methods employed in dressing, dyeing and improving the skins; and the rules by which the experts determine their values. Considerable time has been devoted to the prepara tion of a map showing where the finest specimens of the North American mammals are obtained, and to the compilation of a Lexicon giving the English, French, German and Spanish names of the different animals, and the trade designations applied to the furs made from the various pelts.

Book Description
Excerpt from Fur-Bearing Animals: In Nature and in Commerce This work is intended, firstly, to aid persons engaged in trade to recognize readily, and to have a closer knowledge of the animals with which they are to some extent already familiar, and which they would have some difficulty in finding in more elaborate and scientific works. Secondly, to be a connecting link between commerce and science. The scientific portions of natural history are often described with much detail, but, though interesting and important, they should not altogether close our eyes to the relations which the animals bear to man, and the important part they play with regard to his clothing and, consequently, to his personal comfort. The Author has also endeavoured to make this work more interesting to the general public by adding small sketches of the habits of the animals described.

Book Description
Excerpt from The Fur Animals of Louisiana HE taking OF furs for clothing and the trading in T pelts is undoubtedly the Oldest industry in the world. This activity goes back many thousands Of years into the dim reaches Of the Stone Age when the cave man, crude hatchet or club in hand, killed the beasts of the field so that he and his family could have covering during the rigorous seasons of the year, and one may be safe in claim ing that the Neanderthal Woman was the first to choose the handsomest pelt for keeping her flesh warm and for enhancing her physical charms.

Book Description
Excerpt from Animal Breeding Breeding a Science and an Art - Animal breed ing is at once a science and an art. It is a science in so far as it discovers and systematically arranges the truths and principles which relate to the improve ment of live stock. The value of in-and - in breeding, for instance, as a quick means of improvement illus trates such discovery. (see Chapter X.) It does not appear to have been known to the ancients. If it were thus known the knowledge was subsequently lost. The systematic arrangement of the truths and principles which relate to the science is yet far from complete, and it may be added, that many of these truths and principles are not yet understood. It is an art in so far as it successfully uses those principles in effecting improvement. The importance, there fore, of understanding the principles which make improvement possible will be at once apparent, since, until so understood, they cannot be turned to profit able account.
