THE WALNUT. 213 



bushels." It is unnecessary to search for further proof 

 to show that certain excellent varieties of the Persian 

 walnut do thrive and bear abundantly in our Northern 

 States ; not, perhaps, in the extreme boreal borders of 

 New England, nor in those of the northwest, but the 

 acclimated sorts are pretty safe as far north as 42 

 of latitude, and in protected locations may crowd up a 

 half degree more. I have found very productive trees 

 of this nut in northern New Jersey, several in Bergen 

 county, others in Passaic, and thence southward, and 

 while they are few in number, they are sufficient to 

 prove that this tree is adapted to the soil and climate of 

 the entire State. We seldom find more than one or two 

 trees in any garden, and these are probably more the 

 result of accident than design, their owners seeming to 

 be satisfied in possessing something in the way of a tree 

 not common in the neighborhood, never thinking that 

 it might be well to plant enough of such trees to have 

 them become a source of revenue. The parentage of 

 quite a number of these bearing trees is readily traced 

 to the Morris and Tieman stock, showing that these old 

 trees are of a hardy and prolific race, which are well 

 worthy of perpetuation for cold climates. Very old and 

 large walnut trees are reported as growing in Pennsyl- 

 vania and other of the Middle States, but they are far 

 from being numerous. It has long been claimed that 

 this species of nut succeeded best in the Southern States, 

 and it is probably true, especially with the tender varie- 

 ties ; but for some reason, unknown to me, they have 

 not been planted there in sufficient numbers to have, as 

 yet, become of any commercial importance. 



During the past twenty-five years these nuts have 

 been more extensively planted in California than else- 

 where in the United States, and we may expect soon to 

 know something definite in regard to results. Nearly 

 all of the favorite French varieties have been introduced,
