Popular information is given for using the above table in selecting 

 feeding stuffs, and remarks on the factors which influence the composi- 

 tion of crops. Under the latter topic analyses are given of timothy cut 

 at 3 different stages to show the effect of stage of growth on com- 

 position. A sample of timothy weigliin g 25 lbs. was exposed to 1 heavy 

 shower and 3 heavy dewfalls. At the end of 5 days the hay weighed 

 21.5 lbs. The percentage of each nutrient lost by exposure was, ash 

 17.26, fat 7.47, protein 7.G9, fiber 0.20, nitrogen-free extract 25.78. " The 

 rain removed 12 per cent of the best part of the dry matter of the 

 hay. . . In actual haymaking the loss would have been larger, because 

 some of the hay would have been lost mechanically." 



The digestibility of wheat, H. Snyder {Minnesota Sta. Bui. 36, pp. 

 140-148). — The digestibility of wheat was determined by feeding it to 

 young pigs (1) whole in connection with cracked corn and (2) cracked 

 in connection with corn. Only the average results of the trials are 

 given, which are as follows:
