it has supplanted that variety for forcing. 

 Farquhar is a new candidate that proves 

 scarcely as dark in color as the intro- 

 ducer claimed, however, it is 



grower, distinct in color and foliage; 

 well worth further trial.

KATSURA TREE — Cercidophyllum Japonicum. 



"r^ICH as we are in native species 

 ^i of trees and shrubs, each having 

 ,I\i. its own peculiar charm, there is 

 always great interest and delight 

 in growing those from foreign coun- 

 tries, especially when proved to be of 

 exceptional merit. 



The katsura tree, although introduced 

 into the United States more than twenty 

 years ago, has not yet found its way to 

 many Canadian homes ; but anyone 

 who sees this graceful tree cannot but 

 have the desire of possessing a speci- 

 men. This tree has been tested at the 

 Central Experimental Farm, Ottawa, for 

 seven years, and has proved perfectly 



hardy. It is of pyramidal form, branch- 

 ing thickly from near the ground ; the 

 leaves are heart-shaped and red-veined, 

 somewhat resembling those of the Judas 

 tree (Cercis canadensis), and are very 

 pretty. 



The specimens at the Experimental 

 Farm have not bloomed yet, but we 

 learn that the flowers are small and 

 inconspicuous. The katsura tree is 

 closely related to the Magnolia family. 

 In Japan, of which it is a native, it 

 attains a height of from 75 to 100 feet, 

 and is a rapid grower.

EGGLAYING OF THE CODLIN MOTH. 



rROF. Slingerland has been investi- 

 gating the habits of the Codlin 

 Moth. He finds that the egg is 

 deposited upon the side of the 

 fruit, and not in the calyx. It is a 

 little smaller than a pin-head, flat- 

 tened and transparent, so that the color 

 of the apple shows through it. Under 

 the microscope the surface is marked 

 with lines, and looks like a fish scale 

 At first they were difficult to make out, 

 but afterwards easy. 



After careful investigations he found 

 hundreds of eggs in the orchard, scat- 

 tered over the fruits. The young worm 

 was hatched out in about ten days, and 

 at first is little larger than a hair. It re- 

 mains on the surface several hours, then 

 crawls about till it reaches the calyx. 



where it works its way between the lobes, 

 and enters the cavity. 



The practice of spraying as soon as 

 blossoms fall, is effective, because the 

 calyx lobes are then open and the Paris 

 green is readily deposited within the eye, 

 and as the worm does not eat till it en- 

 ters the eye, its first dose will be its 

 destruction 



The closing of the calyx and lobes 

 soon after spraying is an advantage, be- 

 cause it keeps the poison from being 

 washed away by rains ; but if the spray- 

 ing is delayed till after the calyx closes, 

 it will not be so effective. 



The second brood does not always 

 enter the calyx, but eats in the side of 

 the fruit, especially if protected by an 

 overhanging leaf
