Wilson — The Lihentance of Milk-Yield in Cattle. 113 



work represented hy this paper can only be regarded as, in some degree, 

 clearing the ground for the future. 



In addition to the gentlemen mentioned in the body of the paper, there 

 are many others to whom the writer is indebted for kindness and information. 

 It is impossible to name them all, but he would wish to name specially 

 Mr. Mansholt, of the Dutch Department of Agriculture ; Dr. J. G. Eutlierford, 

 at Ottawa, and his assistants ; Professor Wentworth, of the Iowa State 

 College, Ames ; Professor G. P. Grout, of the Minnesota experiment station, 

 St. Paul ; Governor Hoard, Fort Atkinson, Wisconsin ; Mr. Robert Hobbs, Jr., 

 Kelmscott ; Mr. Howie, Secretary to the Ayrshire Milk Records Associa- 

 tion; and the following Ayrshire breeders: Mr. Adam Montgomerie, 

 Mr. Michael Logan, Mr. Thomas Clements, Mr. J. Moffat, Mr. W. H. Ralston, 

 Mr. H. W. B. Crawford, and Mr. James Dunlop. 



Note : — Throughout this paper yields have been expressed, according to 

 the usual custom, in gallons rather than in pounds ; and where pounds have 

 been recorded in a herd-book or by a breeder, the figures have been divided 

 by ten. This involves a slight inaccuracy. It raises British yields by about 

 a thirty-third and depresses Danish by about an eleventh.
