Proceedings of the Fabmebs' Club. 459 



mentioned some weeks ago, as used in Germany, for sticking cattle 



when distended from colic. It is a barb, covered by a canala or 



sheath, except at its sharp end. The barb is a mere round spike or 



dagger, with sharp point. The canala is hollow, having a rim or 



shield at one end, and fits tightly to the barb. The whole is like a 



straight sword with scabbard, the scabbard being cut off a half inch or 



' more from the point. The canala is put on the barb ; the barb and 



canala are then inserted in the side of the animal. The barb is then 



withdrawn and the canala left in the hole. Through it the fluids or 



gases pass out. The shield or rim prevents its dropping in, and the 



canala itself prevents the hole closing or any foul matters going into 



the stomach. The name of this surgical instrument is written some 



times, trochar. 



Subsoil Plows and Plowing. 



Mr. M. C. Weld spoke upon this subject, and exhibited a plow. 

 He said : The advantages of subsoiling can hardly be too highly 

 extolled, and they have been a favorite theme of agricultural writers 

 for many years ; but when farmers come to put these fine theories in 

 practice the cost was too great, and the implement was invariably 

 thrown aside. Of his plow he said : The share or mole is so formed 

 that it enters and passes through the ground easily. In so passing it 

 lifts and cracks the soil on all sieves of it, while that portion of the 

 soil in immediate contact with the share is packed hard on each side 

 by the first two-thirds of the share, and this compacted soil lifted by 

 the wines or flanges on each side to form a more or less firm arch 

 after the passage of the standard, thus acting like a horse-shoe tile, 

 and preserving the track of the plow like a mole-track for a long time 

 — an open channel for air and water to circulate. 



Mr. P. T. Quinn — I do not call this plow new ; I saw the original 

 in Boston sixteen years ago, and have had one in use on my farm 

 for thirteen years. It was invented by the late Prof. Mapes. If any- 

 thing, mine requires less power to draw it. 



The Chairman said that while upon the plow subject, he had a 

 letter asking the Club to recommend a plow. He would state that 

 the Club did not recommend anything, but invited exhibition and 

 competition in farm implements. 



Mr. A. S. Fuller — And desired to encourage excellence and 



improvement. 



Black Moths. 

 Mr. A. C. High, "White Deer Mills, Penn. — Our house is most pro- 

 digiously infested with the black moth, eating carpets and everything 

 else. What shall I do ?
