A TREATISE ON NUT CULTURE. 



five minutes and cracking by a slight tap while still 

 hot, the thin shells readily part and the kernel can 

 be extracted whole, which feature will render 

 them valuable. The meat is very sweet and will 

 be much used by confectioners. 



Juglans Mandschurica. This species resembles 

 the foregoing two in habit of growth and differing 

 but little from the American Butternut. The nut 

 is also more of the character of the Butternut, the 

 shell being thick and rough.

CALIFORNIA BLACK WALNUT. 



This tree is described as attaining a height of from fifty to seventy-five feet 

 and two to four feet in diameter. Nut is round; kernel sweet and good flavor; 

 shell smoother than the Eastern Black Walnut, .though shell so thick as to 

 render the nuts of little market value. The tree, however, may prove valuable 

 as a stock on which to work the Persian Walnut in sections where the latter 

 does not succeed. 



SIBERIAN WALNUT. 



From Meehari*s Monthly. 



It is said that the Siberian .Walnut (Plerocarya Caucasica] , has edible nuts 

 of as much value as some other members of the Walnut family. The tree has 

 been found quite hardy in the Northeastern parts of the United States; but so 

 far as known, no specimen has fruited in this country. It differs from our 

 ordinary Walnut and Hickory in having wings to the husks. It was this that 

 suggested the name of Pterocarya. 



A USEFUL INSECT. 



From Meehan's Monthly. 



Mr. P. H. Strubler, of Naperville, 111., sends some Black Walnuts that 

 have had the shells completely hollowed out by some insect, in an early stage. 

 They have not entered through the shell to the seed, so that the Walnut is 

 not in the least injured for edible purposes, but rather given an advantage, for 

 after this skeletonizing by the insect the shell can be cracked with little more 

 force than would have to be employed on a rather hard Almond.
