In general, no systematic records were kept of pelt production, breeding, and pedigree, and for this reason prospective buyers are compelled to rely largely on the word of the seller. A few breeders, however, have been far- sighted enough to see that records regarding the quality of fur produced are necessary to the successful conduct of fox breeding as a business. There is probably nothing that will make more for progress than the systematic maintenance of the breeding -record of promising foxes based on the production of a high quality of fur. \, A/APE Off A/£C/f 3/lf/C /n/A/ | PUMP TA/L ffEAD H/P BPUSP T/P.

An inferior fox of good pedigree is in every way prefer- able to a better-appearing individual of unknown ancestry. The selection of either of these individuals as a breeding fox might prove disastrous, but the latter offers by far the greater chance of unsat- isfactory results. The best test of the breeding powers of a fox is to see the progeny. Rarely are a pair of foxes of proved excellence as breeders offered for sale, and selections must generally be made from untested stock on the basis of individuality and pedigree. The value of particular individuals in the pedigree depends on the de- gree of relationship. A good sire or dam is a very important con- sideration; the grandparents, when judged by themselves, do not have so much weight; and remote ancestors need hardly be taken into consideration. 7 Bull. 905, IT.
