Colic or horses, H. J. Dktmers, M. V. D. (pp. 21-69). — This is a 

 tfcatise on colic of horses — causes. syni[)t()i)is, diagnosis, prognosis, 

 treatment, and j)i-e\X'ntion. 'J'he author believes that '' The real pre- 

 disposing cause of colic, or the real cause Avhy horses sutler so much 

 more frequently than othei' aninuds. must he foiuid in the exceedingly 

 fre(iuent occurrence of aneurisms in the anterior mesenteric artery." 

 The aneurisms are caused In' small worms {Sclerostomum equinitm, 

 Kud., or ^Stroiujylii.s aniuitns) . Professor Bollinger, of Munich, is 

 referred to as having found worm aneurisms in 49 per cent of all 

 horses examined, and in 90 to 94 per cent of all aged horses. Such 

 aneurisms were found in twenty out of tAventy-one horses examined 

 at the Station, or in 95 per cent.

HlMoneal. — In ccmnectioii with a brief account of the first use of 

 the silo in this country and abroad it is stated that — 



The extravagant claims at tirst iiuulc ti.v silo cutliiisiasts led pi-at-ticnl fanners 

 and clieniists alike to denounce the method as both impracticable and iinscien- 

 titic, but farmers have discovered improvements in the methods of producing, 

 Itrcscrviiit;. and feeding silage, while chemists have demonstrated wide differ- 

 ences in the chemical composition, and consequently in the nutritive values of 

 different forms of silage, so that the silo, which at one time seemed to be losing 

 ground, is to-day generally recognized as a very useftil adjunct to the equip- 

 ment of ever.y dairy farm, and to many farms where dairying is not the chief 

 pursuit. 



Location., fofiii. (I lid sh:e of aUo. — If possible the silo should be 

 under the same loof with the feeding place. In most dairy barns the 

 cows are in stanchions in two long rows facing each other. In this 

 case the most convenient place for the silo would be at the head or at 

 one side or the other of this feeding room ; or. if iieither of these 

 localities can be used, directly back of and inside or outside of the 

 building. A portion of a root cellar in a bank barn might be con- 

 veniently partitioned off for a silo, or the floor t)f a root cellar under a 

 haymow might be moved and the silo extended upward 8 or 10 feet 

 above the bai-n floor. As to form, in the opinion of the author the 

 most economical silo is one with its longest line fi-om top to botttmi, 

 because less surface will be exposed while the silage is being fed. The 

 size of the silo should be in pro])ortion to the size of the herd to be 

 fed from it. Whether the silo should be di\i(led will depend upon 

 the relation between the size and the number of cattle. For example, 

 if twenty cows are fed from a silo -20 feet sciuaiv it would be better 

 to divide it. but if the herd is increased to forty and fed from the 

 same silo a i)artition is not especially desirable. If two different 

 croj^s. as foddei- and clover, are fed from the same silo it is better to 

 place each in a separate compai'tmeiit.
