present; and park trees with over 100 feet and 28 to 36 inches 

 diameter make this one of the most rapid persistent growers. It 

 is a very lightneeding tree and a treatment Hke oak probably will 

 produce the best results. 



A number of the old trees were measured and their volumes 

 calculated, showing for dominant trees in the average 25 inch 

 average diameter and 178 cubic feet contents. 



As to acre yields no experiences are as yet attainable, but from 

 the above data and comparisons of many young stands, measure- 

 ments of which are given, the promise of greater results than 

 from the native oak is most favorable, the walnut accomplishing 

 in half the time, that is in an 80 year rotation, the dimensions of 

 the oak. 



The prices paid for nigra wood, 4 trees, down to 3 inch diame- 

 ter averaged 70 cents per cubic foot, more than double the price 

 for oak of like class, and, as this is attained in half the time the 

 walnut financially is 14 times more profitable than the oak. This 

 was an ordinary average price, which may be doubled and trebled 

 for the better logs. 



In addition to the wood the nuts are of value, naturally those 

 of regia more than nigra. The latter fruits early; the outside 

 trees on the south side of an 18 year stand have already borne 

 fruit for four years. From various measurements taken from old 

 trees it appears that trees in full mast may bear as many as 4,500 

 nuts and in the average 2,000 nuts ; full masts occurring ap- 

 parently every four years; other years 200 to 600 nuts may be 

 secured. The size and weight vary greatly, so that from 30 to 60 

 nuts go to a pound, hence it is best to buy by number, $2 to $3 

 being paid per M. In the forest the yield will, of course, be 

 smaller, yet it is calculated that a 60 to 70 year old stand may 

 furnish with only 70 trees (32-40 hi.) 195-120 bushels and $3 to 

 $4 money return. 



If it is added that these nut trees have the fewest enemies ex- 

 cept a few half innocuous leaf insects and borers (and in Ger- 

 many the all destructive May beetle), the species are among the 

 most promising of the broadleaf tribe.
