that the appHcation should he made 

 early, as soon as the young Canker 

 Worms appear. I know of nothing 

 better to do than to repeat the spraying, 

 being sure to add to the Paris green an 

 equal amount of fresh lime, so that the 

 trees may not be injured. 



There are two species, Aiiisopteryx 

 Vernata is the spring Canker Worm, 

 which usually does not escape from its 

 cocoon until spring, see Fig. 1152 (/) 

 male, {g) female ; {c\ the worm which is 

 olive green or brown ; and {b) eggs, dark 

 with a small cluster of eggs natural size 

 near at {a\ and {d) a chrysalis. 



The other is Auisopteryx poi/ietaria, 



the fall Canker Worm, which is easily 

 distinguishable from the former, by 

 observing the differences in any stage of 

 development, as e. g., the shape of the 

 egg, or the markings of either the male or 

 female moths. The latter appears to be 

 the one more commonly met with in the 

 Niagara peninsula. 



Hitherto our Superintendent of Spray- 

 ing for Ontario, has directed his efforts 

 almost wholly against codling moth and 

 apple scab, two of our ills ; but we be- 

 lieve it would be well to make one or 

 two special experiments on the destruc- 

 tion of the Canker Worm. 



MAULE'S JAPANESE QUINCE— PYRUS JAPONICA 

 MAULEI. 



THE Japanese (|uince, Cyrus japonka 

 or, as it is often called, Cydonia 

 japonica, is a very beautiful and 

 desirable shrub where the climate is not 

 too severe ; but at Ottawa, where the 

 winters are very cold, it is quite unsatis- 

 factory : the wood killing hack more than 

 one half and the flower buds only sur- 

 viving when well protected, and rareb' 

 more than a foot above the ground. A 

 more recently introduced variety, P. Jap- 

 onica Alauki is t]uite hardy at Ottawa. 



the leaves starting from the tips of the 

 branches and the flowers being much 

 more abundant than in the common 

 species .\ hedge of this pretty shrub 

 at the Experimental Farm has been 

 almost covered with bright red blossoms 

 since May loth. It fruits freely and in 

 the autumn the yellow quinces make it 

 ver}' attractive. These have a strong, 

 pleasant, aromatic odor, but are usually 

 considered as unfit for food.
