 TIIK TREK C'RK'KET. 



Sir, — Enclosed you will fiml a cherry slip, with some eggs. I found several of them 

 on my tree*, and would like t<> know, through the Canakian Hortutlti kist, what they 

 are ? 



W. S. Short, London, Ont . 



The twig of cherr)' tree sent us is full of eggs of the Tree Cricket (CEcanthus 

 niveus). The insect will do very little injury to the cherry tree, but it is one of 

 the most troublesome insects in the ra.spberry plantation.

Towards the end of the summer the female moth, desirous of placing her 

 progeny in a safe place, chooses the young and tender wood of the plum, cherr)-, 

 or other trees, and more particularly the raspbepry bushes, in which to deposit 

 her eggs. By means of a long ovipositor, she is able to place them in the young 



wood in long rows, each 



standing obliquely, as shown 



in Fig. 42. The mature in- — ^*"~^?'^9J\V. 



sect, with its ovipositor, is Ki«;. 4.S. 



shown in F'ig. 44. 

 The young insects hatch out about midsummer and much 



resemble the perfect insect, except that they have no wings. 



They do no further injury to the raspberry bushes, their food 

 Fk;. 44. being plant lice and ripe fruit. About the only remedy is 



careful attention during the winter in cutting off and burning the injured 

 branches. 



USE OF COAL ASHES. 



SiK, — I sifted coal ashes in my cow stable, as an absorbent. W'liat etlect will it have 

 npon thf manure as a fertilizer ? 



<J. W. HoiMJKTTs, St. Cafharhii -^t Out. 



Coal ashes are a very good absorbent, and, so far as wc know, would not 

 have any injurious effect, used as our correspondent proposes. Coal ashes con- 

 tain no great elements of fu-rtility in themselves, but they have a mechanical 

 effect upon the soil, which sicms in sonn' cases to In' favorable to the growth of 

 vegetation.
