The Journal of Heredity- 



is not given. However, it does show- 

 that even at that time black and white 

 cattle were accepted for registration. 



Brown as used in these tabulations 

 includes all shades of red and likewise, 

 for convenience, red and white animals 

 are tabulated with those that are brown 

 and white. It may be assumed that 

 the terms brown or white as used in the 

 herd book do not always refer to a self 

 brown or self white, but rather to 

 animals that would ordinarily be called 

 brown or white b}^ the casual observer. 

 For example, some of the so-called 

 white cows have brown eye lashes and 

 dark colored eyes which would not be 

 present in a true self white. The 

 designations brown and white, and white 

 and brown are freely used in the herd 

 books, the former apparently referring 

 to animals appearing more brown than 

 white and the latter to those showing 



more white than brown, but it would 

 seem as if there would be many cases in 

 which it would be hard to determine 

 which should be used. 



A comparison of Tables I and II shows 

 a decrease from 1886 to 1913 of about 

 10% in the number of white and brown 

 cows. Table II shows a remarkable 

 similarity in the per cent, of cows and 

 bulls of the different colors, which is 

 not the case in Table I. It is probable 

 that this difference may be largely due 

 to greater care being exercised in the 

 later registration work. Table II also 

 shows that there are only about one-half 

 as many black and white cows as 

 either red or white. 



Table III shows in more detailed 

 form the marking of the bulls referred 

 to in Table II, as they are entered in 

 the herd book. It brings out an inter- 

 esting point that is well known among 

 Ayrshire breeders and exporters, namely,
