 ends of the hair become coated with resin; after that, retouch 

 those parts where the resin is rubbed off. 



Treatment of Dairy Calves after AVeaning. Skim- 

 milk can be fed profitably five or six months, and, where milk is 

 available and is not needed for other purposes, even longer. The 

 weaning may be done either gradually or at once. Tests made 

 at this station show that there is practically no difference in either 

 case, as will be seen from table XXII.

The calves weaned gradually made more fuss than those 

 weaned abruptly. In these cases the allowance of grain was 

 •continued when the skim-milk was taken away. 



If pastures with plenty of feed, shade and water are avail- 

 able, young dairy stock could ask no better quarters. If pas- 

 tures become dry and scanty, it would be well to give them what 

 they will eat of alfalfa, red clover, or cow-pea hay. These nitro- 

 genous feeds can be supplemented by sorghum, corn stover, Kafir 

 corn stover, millet, orchard grass or millet hay, but there should 

 always be plenty of leguminous crops, so as to furnish plenty of 

 protein to develop bone and muscle. Where plenty of protein 

 is furnished in the roughness, heifers intended for the dairy need 

 little or no grain. In fact, it is advisable to give them bulky 

 foods, so as to develop large paunches. If the calves are weaned 

 in winter they should be fed plenty of nitrogenous feed. At
