BASTAED OF THE DEMIJOHN COW. 



When the streaks marked F F are found in the Cow of this Class, of the di- 

 mensions specified in the description of the Bastard of the Curveline Cow, they 

 serve here also to detect the Bastard Cow ; and l;er badness in regard to the rapid 

 loss of her milk will be in proportion to the size of these streaks. The smaller 

 they are, the less defective will she be in this respect. (See Plate IX. Fig. 6.) 



CLASS VI. 

 aije Square- Sxntcljeon Com. 



The name indicates the appearance of the escutcheon, the upper part of which 

 is shaped like a carpenter's or mason's square. 



•HIGH COW. 



First Order. — Cows of this Order and Size yield, while at the hight of their 

 flow, sixteen litres a day, and they continue to give milk until they are eight 

 months gone with calf. 



The skin within the escutcheon is of the same yellowish color as in the supe- 

 rior Orders of the preceding Claisses. The udder delicate, covered with short, 

 fine hair. The escutcheon begins as in the foregoing Classes ; and, rising from 

 just above the hock joint, on the inner surface of the thighs, spreads outward to 

 the points A A. (See Plate VI. Order 1.) Above those points it represents a 

 square. A right line runs across to the points J J, distant from each otiier from 

 five to six inches. Thence the figure is bounded by two right lines, which meet 

 in an acute angle at the point E, distant about two inches from the vulva. Above 

 that, to the left, the figure of a square is formed by two streaks of hair, E B ac'l 

 B C (the point C being at the orifice of the vagina) ; the former of which is about 



} four inches long, by an inch and a quarter wide, and the latter from five to six 



* inches long, by somewhat less,than the same width.
