used in judging oranges. Ten points 

 were given to each of the characters, 

 of which five were grouped as 

 "physical" and five as "juice" 

 characters. 



It is high time that the subject of 

 judging fruits at fairs was fully dis- 

 cussed at our meetings, and a com- 

 mittee of our best pomologists ap- 



pointed to draw up a scale of points 

 to aid judges in estimating the com- 

 parative merits of our apples, peas, 

 grapes and other fruits. 



Mr. Thomas Beall, of Lindsay, 

 has promised to contribute a paper 

 for our Summer meeting under this 

 head, and we hope the subject will 

 at that time receive full consideration.

The Tree Cricket. 



33. Three pieces of Cuthbert raspberry 

 canes aftected by some kind of borer, of 

 which I have seen no account in print. This 

 borer, as you will see from the enclosed 

 pieces of cane, lays its eggs one season to 

 hatch in May or June of the next. Last 

 season was the first we noticed them, 

 and we at once cut all we could find and 

 burned them ; but this season, they are, if 

 anything, worse, and we would like to know

what to do to get rid of them. Can you, 

 Mr. Editor, or some of our professors, en- 

 lighten us? — Edgar Husband, Cainigori)t. 



The raspberr}' canes were duly re- 

 ceived. The injury is done by the 

 depositing of its eggs in the Autumn, 

 by the Tree Cricket, known to botan- 

 ists as .■EcaiitJiits iiiveits. The female 

 beetle is furnished with a long oviposi- 

 tor, by means of which she makes 

 an oblique opening half way through 

 the cane, and there places one of her 

 yellowish, semi - transparent eggs ; 

 this operation she continues, placing 

 the eggs neatly side by side, in num- 

 ber anywhere from five to fifteen. 

 These eggs are easily exposed to view 

 bj' splitting the stem (see fig. 38), and 



are quite interesting subjects for the 

 microscope, about one-eighth of an 

 inch in length and having a peculiar 

 granulated head. About midsummer 

 the young insects hatch out. The per- 

 fect insect is a little more than half 



an inch long, and is shown in our 

 illustrations, fig. 36 representing the 

 male, and fig. 37 the female. Both 

 are lively fellows, but the males are 

 musical, chirping merrily all day. 



Canes affected are weakened so 

 that the crop is materially affected, 

 many breaking off completely with 

 the weight of foliage in the spring.
