Papa and mamma pear psyllas are now hibernating in the crevices 

 of the bark on the pear trees. Mother nature is depending upon these 

 to start the broods of young nymphs or baby psyllas which will suck out 

 the life of many pears, and even of some whole trees, in 1899. The above 

 instances are only a few of the many among our well-known insect foes, 

 which might be cited to illustrate the varied and interesting methods 

 pursued by these little creatures to get through that portion of the year 

 when almost everything is in the clutches of Jack Frost. Insects have 

 no Christmas or New Year to look forward to during this cold period, 

 and there is no Santa Glaus to arouse curiosity and wonderment in their 

 sleepy little brains. — M. V. Slingerland. Kural New Yorker. 



BISULPHATE OF CARBON AND TPtEE-ROOT LICE. 



At a recent meeting of the Ohio State Horticultural Society, Prof. 

 Webster stated that he had experimented with bisulphate of carbon to 

 exterminate lice on the roots of trees. Invariably when he applied suffi- 

 cient bisulphate of carbon to kill the lice the tree also died. The pro- 

 fessor remarked that the ants burrow down along the trunks of the trees, 

 then follow the larger roots until they arrive at the soft and tender root- 

 lets and there deposit the lice. 



In regard to fumigation Prof. Webster remarked: 'T would rather 

 have a certificate of fumigation of nursery stock than one of inspection." 

 The professor exhibited a model house for fumigation. He cautioned 

 the audience to be very careful on account of the deadly invisible gas 

 employed. The hydrocyanic gas used is formed by dropping potassium 

 syanide into sulphuric acid and water. The moment these two ingredi- 

 ents come in contact they form an invisible deadly vapor. The model 

 house that the professor exliibited was so constructed that the danger from 

 mixing was avoided. — Prairie Farmer.
