202 ANNUAL REPORT. OF THE Off. DoC. 



Dll. ARMSBY: I don't think 1 cau ausvver that (luestion better 

 thau by retVrrinj^ you to the work of the New Jersey Sta- 

 tion and particuhu'ly to their Bulletin No. 158, which gives a series 

 of rotations of silo crops, supplying considerable protein. In general 

 terms I can say, raise leguminous crops such as oats and peas or the 

 soj' bean of the eowpea or alfalfa. Dr. Voorhees gives a list of four- 

 teen dilierent sets of crops; there they grow two and three crops a 

 year on their soiling and plots and arrange them in such a way that 

 they have a continuous supply of green forage throughout the year. 

 We are w'orking out that same problem here but we have not com- 

 pleted the work yet. 



MR. M. P. HALLOWELL, Bucks County: Are pumpkins of suffi- 

 cient use to the dairy cow to admit their culture and use with other 

 feeds? Should the seed be removed before feeding them? Have 

 they any protein? 



DR. ARMSBY: Pumpkins are not particularly rich in protein and 

 it would not pay to raise them if you wanted them simply for pro- 

 tein. I think some of the others would be a better judge than I 

 whether it W'Ould pay to raise them generally; as to the seeds, I sug- 

 gest you refer that to somebody who has had experience with that. 



MR. HALLOWELL: We had quite a discussion come up about the 

 pumpkin and I asked that question for information. Some man said 

 that if a man would plant pumpkins in his corn, he would get a gun 

 and go after him. 



DR. ARMSBY^: Pumpkins are a good dairy food, but not a source 

 of protein particularly. 



MR. BOND: I spent four years from time to time off the farm in 

 the village and I resolved upon an experiment. 1 tied up a milch 

 cow and the heifer for beef in the stable and I fed them both noth- 

 ing at all but corn meal and pumpkins for ninety days and we didn't 

 remove a seed, and we never had a more satisfactory supply of milk 

 nor better butter than we had during that time. My wife packed it 

 and kept it for six months and the beef heifer made the very best of 

 beef, and she never drank but four gallons of water in the ninety 

 days. The cow would drink a little water occasionally, about every 

 other day. I think that entirely exploded the theory that the seeds 

 were injurious to an animal. I would not discard the seeds; we are 

 feeding them now, the sweet pumpkin by the bushel, with the very 

 best of results. 



PROF. HAMILTON: The statement I believe was made that the 

 entire quantity of nitrogen that is taken in is excreted. Are we
