The land, after the crop was taken off, was left in better con- 

 dition than when before prepared for planting ; the second crops 

 receiving no additional manure, except sometimes a light appli-

CHEAP PREVENTIVE OF CANKER WORMS FROM APPLE TREES. 



Solon Robinson.' — I have in a letter from Maiden, Mass., one of 

 the most sensible plans for a cheap preventive of canker worms 

 which climb the boles of apple trees, that I have ever seen. Here 

 it is : 



" Take pine boards of suitable width for four to box a tree. 

 Cut them in pieces two feet long on one edge, and four feet long 

 on the other edge. Nail them together in a box around the tree, 

 with four sharp points up. The box is to be adjusted about the 

 tree before the grubs come from the ground, and a peck of pow- 

 dered lime or ashes thrown between the trunk of the tree and the 

 inside of the box. The caustic lime or ashes will destroy the 

 grubs near the tree, and the boxes will invite all the grubs near 

 them to ascend and deposit their eggs. I found the pinnacles 

 covered with grubs and eggs, and the insects apparently con- 

 tented with this highest point as a safe place, and there the eggs 

 were deposited. I then removed the boxes to a considerable dis- 

 tance from the trees, and heard no more from canker worms ; 

 they all died for want of proper food." 



FINE SHOW OF FRUIT. 



W. S. Carpenter made a beautiful show of Apples and Pears, 

 now in season, embracing the following apples : 

 • Sine qua non, Mahomet, Hollow Crown, Giffard, Yellow Harvest, 

 Strawberry, Red Astracan, Sweet Bough, Early Joe. 



And the following Pears :

 bearing, of the second crop. 



Mr. Carpenter stated that he has now growing in his orchards 

 200 sorts of Apples and Pears, which he has had planted within 

 10 years, and which will now produce a profitable crop.
