Experiments in Ensilage. Professor W. 

 A. Henry, of the Experimental Farm of the 

 University of Wisconsin, has published a 

 report of an experiment in ensilage that 

 was made last year under his direction. A 

 pit was made, thirty feet long by fifteen 

 wide and fifteen deep, with thick stone 

 walls, at a cost of $413.12, and was filled 

 to near the top with a crop of fodder-corn 

 that had been raised and cut up for the 

 purpose, weighing 150,222 pounds, and at 

 the top with second-crop clover just as it 

 came from the field, all under the inspection 

 of many visitors who had been invited to 

 witness the process. " The comments," 

 says Professor Henry, " were as varied as 

 the visitors. As the weather was very 

 warm the ensilage heated rapidly, and when 

 the visitor would run his hand down into 

 the mass of damp-cut fodder, and find it so 

 hot as to be uncomfortable, there would 

 sometimes come a shake of the head and 

 prediction of failure of some sort : ' It will 

 burn the barn up ' ; ' May keep below, but 

 will not on top ' ; ' Think it will be all right 

 above where it can get some air, but below 

 it will make a nice manure-heap.' " The 

 silo was loaded down with an unusual 

 weight of stones, in order to bring the 

 more pressure to bear upon the long and 

 matted clover-stalks ; for the efficacy of the 

 operation depends upon the prevention of 

 heating by cutting off the access of fresh 

 air. After the pit was closed, but little 

 evidence of the change within was seen, 

 only occasionally a just discernible but not 

 at all marked odor. When the silo was 

 opened, November 29th, the clover was 

 partly decayed for about a half -inch down, 

 and moldy for two or three inches below 

 and around the sides of the pit. This was 

 thrown out to be put on the manure-heap. 

 The cows were a little shy of eating the 

 ensilage at first, but after four or five feed3 

 all ate it as naturally as they would hay.
