troublesome to our cultivated varieties of the apples and pears, doing its evil 

 work during the months of July and August. The larva grows to about one- 

 half of an inch in length, remains in the fruit until it is transformed, and then 

 it escapes a perfect insect. 



Prof. Gillette, of the Ohio Experi. 

 ment Station, has been making some 

 observations which are worthy of being 

 quoted here. He says : 



"On June 13 last, I saw a female per- 

 form the entire operation of egg-laying, as 

 follows ; First, a cavity was eaten in the 

 apple (b), taking thirty minutes. The beetle 

 then turned about and applied the tip of her 



away without turning about to inspect her 

 work. I at once plucked the apple but found no puncture in the skin, only a minute brown 

 speck. The beetle had plugged the little opening with what appeared to be a bit of pomace, 

 probably excrement. With a sharp knife a section was made through this egg-chamber, 

 which I have endeavored to represent natural size, as above (b) with the egg at the 

 bottom. Although it is almost impossible to distinguish newly stung fruit from external 

 appearances, it becomes very easy after a few days when the infested apples become gnarly 

 and ill-shapen as above (a)." 



Picking off and destroying the infested fruit is entirely impracticable in a 

 large orchard, and it would be foolish to advise the orchardist to go to work 

 jarring his apple and pear trees in order to catch and destroy apple and plum 

 curculios ; so that really our only hope for the extinction of this insect lies in . 

 the successful application of Paris green in the same way as for the codling 

 moth; and having ourselves, on several occasions, applied it with success, it 

 will require a good many failures to destroy our confidence in, at least, the partial 

 effectiveness of this remedy. 



Apple Orchards in Nova Scotia. — We are in receipt of the Provincial 

 Crop Report of Nova Scotia, dated December, 1 890. From this it appears that 

 the production of apples for the market is chiefly carried on in the so-called 

 apple belt, between the north and south mountains, running through a portion 

 of Annapolis and King Co's. The crop during the last season is below the 

 average, amounting to about 73 per cent, of a full crop. Of varieties, the Ben 

 Davis takes the lead for productiveness, having averaged 91 per cent ; the 

 Rhode Island Greening, and Blenheim Pippin come next with 86 per cent., and 

 next in descending order, are the Golden Russet, Cranberry Pippin, Baldwin, 

 Northern Spy and King. 



This differs from our experience in Ontario, where the Northern Spy has been 

 the most productive variety during the season of 1890.
