Porto Rico Agricultural Experiment Station, and a 20-page publica- 

 tion has been issued as Bulletin No. 2 of that station, in which various 

 remedies are duly recommended and discussed. Like others of its 

 kind, it is subterranean and nocturnal, feeds largely on the roots of 

 plants, and extends its depredations over the entire year. 



As to remedies, clean cultivation, " hilling up," winter and spring 

 plowing, trap lights, and poisoned baits are the best that are recom- 

 mended. Mr. Barrett's bulletin can be obtained by application to the 

 Secretary of Agriculture, and it is not necessary to make further 

 mention of remedies here. 



The southern short-winged mole cricket (Scapteriscus dbbri vt- 

 atus Scud.). — During November and December, 1902, we had cor- 

 respondence in regard to this species with Mr. J. A. McCrory, Miami, 

 Fla. It was described as eating- all fruits that fall to or touch the

earth, and injuring all kinds of vegetables as well as seeds, including 

 Irish potatoes, sweet potatoes, beans, and tomatoes; also as eating 

 dried blood and ground bone in commercial fertilizer. Whole tields 

 of tomatoes were devastated, and the insect even gnawed the roots of 

 orange trees. Young tomato plants were gnawed oil' as fast as set 

 out, and the insects were described as working up the earth like thou- 

 sands of chickens scratching it. Injury began when the crickets were 

 "no larger than a Ilea." They were more numerous along the Miami 

 River and more or less scattered over the southern portion of Dade 

 County, and were multiplying rapidly. Our correspondent stated 

 that it was almost impossible to grow a crop of any kind on account 

 of the destructiveness of this pest. Seed beans were devoured as 

 soon as they became soft after planting. Of L00,000 tomato seeds 

 scarcely one had come up on account of the ravages o( these insects.
