leaves for the table after rains had washed the foliage. The emulsion 

 would also kill the eggs of the leaf-miners which are deposited on the 

 upper surface of the leaves. 



No attack upon the beet itself (root-bulb) could be discovered, either 

 -of insect or of the nematode worms which are infesting the roots of so 

 many of our vegetables and garden plants. Most of the beets seemed 

 unusually small, but their dwarfing, if really such, may have resulted 

 from impaired leafage or soil condition. 



An interesting and valuable paper on the " Insect Enemies of the 

 Sugar Beet " has lately been published by Mr. Lawrence Bruner, Ento- 

 mologist of the Nebraska Agricultural Experiment Station, and con- 

 tained in Bulletin 16, vol. iv, of the Station. For copies, the Station 

 might be addressed, at Lincoln, Neb. 



Diseased Austrian Pines. 



The following communications relate to a diseased condition of Aus- 

 trian pines and some other evergreens, which is not confined to the two 

 localities indicated, but occurs elsewhere in the State, — perhaps more 

 particularly in its southeastern portion : 



Dear Sir. — I send you twigs of Austrian and California pines from 

 trees in this place, showing disease, and beg the favor of information 

 and advice either written or printed. This place is the estate of the 

 late Colonel Rowland, who was treasurer of the State in ] 866. The 

 ornamental or planted part is about 60 acres, and the trees were all 

 carefully chosen and planted durii g the war, and ha^e made excellent 

 vigorous growth for thirty years. White pines and others have been 

 struggling with disease for several years, and now are dying by ones 

 and twos. But perhaps something may be done to save the others. 

 The California (Bentham) pine has looked brownish for two years. 

 The Austrians seem a case o'f sudden decay. The foliage of a whole 

 group looks curled and dry, and boughs here. and there turn brown, 

 then yellow, and are dead. On supposition that it is caused by insect 

 attack, I venture to address your office. A. M. W.

Dear Sir. — I send you by mail a specimen branch of an Austrian 

 ■pine ^Pinus Austriaca) showing the manner in which several of my 

 :finest trees are affected. I can not find the trace of any insect, and I 

 would thank you if you are able to give me any explanation of the
