TREATISE ON MILCH COWS. 57 



escutcheon is distinguished also hy a growth of descending hair (G) on the right 

 thigh, which, hegmning at A, encroaches upon the ascending hair, running into 

 the inner surface of the thigh, to the distance of about six inches. 



Sixth Order. — Cows of this Order yield, during the hight of their flow, nine 

 litres a day, and continue to give milk until four months gone with calf. 



The escutcheon of this Order has the same figure as that of the Fifth, only it 

 IS more contracted at the points A A. On both thighs there is a growth of de- 

 scending hair (G G), which runs into the inner surface of the thigh, forming a 

 triangle, the sides of which are about four inches and two inches in length. — 

 Below the vulva is the same mark (C) as in the preceding Order. 



Seventh Order. — Cows of this Order yield, while at the hight of their flow, 

 six litres a day, and continue to give milk until three months gone with calf. 



In this Order, as is seen in the Drawing, the upper part of the escutcheon is 

 entirely wanting on the right side. On the left side it is well defined, though i>Q 

 a very contracted scale, between the points A and B. On the right side, the 

 lower portion of the escutcheon terminates at a point in the line where the two 

 thighs join ; that is to say, bi a line with the vulva. To the right of this line, 

 ^the only trace of the wanting half of the escutcheon, above the point just men- 

 tioned, consists in a few hairs bristling up against each other. 



In this Order the udder is generally covered with a thin growth of coarse 

 hair. 



Eighth Order. — Cows of this Order yield, while at the hight of their flow, 

 four litres a day, and continue to give milk until two months gone with calf. 



The escutcheon is the same as that just described, only yet more contracted 

 and imperfect. Here and there, on each' side, a few scattering hairs bristle up 

 within the space occupied by the escutcheon in the more perfect Orders. 



What has been said of the distinctive marks of the several Orders of this Class 

 holds good, whatever may be the size of the Cow, except that the dimensions 

 above given, having reference to tall Cows, are to be proportionally reduced in 

 regard to those of the other two sizes. Respecting the latter, therefore, it is re- 

 quisite to state only their yield and the time during which they continue to give 

 milk. 



COW OF MEDIUM HIGHT. 



First Order. — Cows of the First Order of this Size yield, during the hight of 

 their flow, sixteen litres a day ; and, like those of the High Size, they continue to 

 give milk until they are eight months gone with calf— the yield gradually di- 

 minishing from the time they conceive anew. 



Second Order. — These Cows yield fourteen litres a day, and continue to give 

 milk until seven months gone with calf. 



Third Order. — These Cows yield twelve litres a day, and continue to. give 

 milk, until six months gone with calf. 



Fourth Order. — These Cows yield ten litres a day, and continue to give milk 

 until five months gone with calf. 



Fifth Order. — These Cows yield eight litres a day, and continue to give 

 milk until four months gone with calf. 



Sixth Order. — These Cows yield five litres a day, and continue to give milk 

 until thrae months gone with calf. 



Seventh Ordhr. — These Cows yield three litres a day, and contmue to give 

 milk until two months gone with calf.
