greater variety of soils than the heart cherry trees ; and 

 may be employed as stocks for the latter in unfavorable 

 situations. The outgrowing of the stock by the graft, 

 constitutes no valid objection. We have never seen a 

 tree endangered by such overgrowth, while the obstruction 

 to the descent of the juices, favors the enlargement of the 

 fruit. 



The apricot was formerly ranked with the plum, but 

 it differs enough to stand separate. Like the plum how- 

 ever, it has a smooth stone, and turns sour with heat ; 

 though in flavor it resembles the peach more than any of 

 our fruits. It resembles it also in the excitability of the 

 fruit buds in winter. Its earlier bloom exposes it rather 

 more to severe weather in the spring, but generally it 

 succeeds wherever the peach can be successfully culti- 

 vated. In this climate, the tree is perfectly hardy. 



There are two species of the apricot; the black, and 

 the common sort, which has spread into many varieties. 

 Ripening earlier than the peach, their presence in the 

 fruit garden is very desirable. 



Neither the borer nor the caterpillar attack the pear 

 tree ; but sometimes flies, wasps, and hornets are busy 

 among the leaves, showing that all is not right, and that 

 honey-dew emitted by plant lice, attracts them. But this 

 tree is subject to a more serious injury, viz : the fire 

 Wight, which occurs early in summer, the leaves from the 

 extremity of the branches for two or more feet, appearing 

 as if they were scorched. We think, however, that two 

 distinct causes occasionally operate to produce similar 

 effects, viz: insects, and a starting of the bark in winter. 



The late Professor Peck, on examining the branch of a 

 pear tree, which had died with fire blight, said the dam- 

 age was caused by an insect, (Scolytus pyri,) and that to 

 cut off the limbs a foot or more below the dead part, and 

 IMMEDIATELY BURN THEM, would be the proper remedy.
