 This gall-gnat may be mentioned as a type of those that 

 make galls on leaves. The galls are at the edges of the leaves, 

 and, as there may be many alongside one another — one larva to 

 each gall — the leaf edges are rolled. Salix viminalis is a 

 favourite host plant, but 5. fragilis may be infested, and there 

 is a record of attack on 5. caprea.

 to short pieces, and bruise it thoroughly, so that when mixed 

 with a small proportion of barley or other grain it would form 

 a suitable fodder for sheep, working oxen, &c. The bruiser 

 ought to be designed for attachment to the thresher, so that the 

 whole process of threshing and bruising may be effected at 

 once. A German bruiser has already been put upon the market 

 this season. It is said to be able to deal with the amount of 

 straw delivered by a 4/6 drum-thresher, the thresher and bruiser 

 being driven together by an 8 horse-power engine.
