CULTURE. 405 



high state of cultivation, and grown or worked on good, healthy 

 seedlings, are rarely subject to it. And a tree diseased by inocu 

 lation may be recovered by appliance of abundant food at the roots, 

 cutting away the apparent knots, and washing the wounds either 

 with salt or copperas-water. The latter is best. And if, also, the 

 whole tree be watered with a solution of one ounce of copperas to 

 two gallons of water, the knots will disappear. 



Defoliation of both seedling stocks and bearing trees, in the 

 months of July and August, we believe is caused by want of some 

 specific ingredient in the soil. We have cured it by dressing with 

 ashes, and by watering with copperas-water as above named. When 

 animal manures and salt have been used, we have never seen the 

 foliage drop. 



JRot or Decay of Fruit is often a very serious drawback to the 

 sanguine expectations of the fruit-grower. We have supposed it to 

 arise from atmospheric influence, and to pervade the fruit in like 

 manner as fever and ague does the human frame, but have been 

 compelled to relinquish this theory. Latterly we are inclined to 

 the belief that it has its origin in too great exhaustion of the sup 

 plies of the tree, by reason of excess of quantity ; as trees that have 

 come under our notice on which only a moderate quantity of fruit 

 was permitted to mature have apparently been free, while those 

 overloaded, and only moderately, or not additionally, supplied with 

 food, have decayed. 



Our friend, Professor Kirtland, with some friends of science, 

 have, however, lately pronounced it a species of fungus. 



INSECTS injurious. The Egeria. which is noted under head of 

 peaches, sometimes, but rarely, attacks the plum. We refer to that 

 head for its remedy. The Curculio, or Plum Weevil. (Rhynchcenus 

 Nenuphar,} is an insect so destructive as in some sections to have 

 caused orchardists to cut down their plum trees and replant with 

 different fruit. Again, there are sections where the insect, although 

 known, appears not to increase, or injure fruit, materially to affect 

 the crop. It was unknown in the Western States until within a few 

 years past, but now pervades all sections, even to destruction often 

 times of the wild plum. It has been thoroughly described in &quot; Har 

 ris s Treatise on Insects ;&quot; and so much is wrjtten yearly relative 

 thereto, that one entire book of four hundred pages would not con 

 tain it. Our accompanying figure represents the insect in its natural 

 size, i. e., about one quarter of an inch long, of a grayish ^^5 

 brown color, the wing-covers forming two little humps, Tjfr^- 

 giving a rounded appearance to it, resembling a ripe hemp- 

 seed. The head has a long rostrum, beak, or snout, projecting, 

 with which it punctures the fruit, as represented by the crescent- 

 shaped mark on the fruit in our engraving. Early in the month of
