walnut will be overtopped. A field crop, such as potatoes, could be grown 

 with the walnut for the first two years. The catalpa should be planted 

 in the spring of the third year. After eight or ten years it may be 

 gradually thinned out, and by the time the plantation is 25 years old 

 three-fourths of the catalpa and all defective walnut trees should have 

 been removed. This will leave most of the walnut trees, but only the 

 best specimens of the catalpa. and at this time the stand will probably 

 not exceed 700 to 800 trees per acre of both species. By the fortieth 

 year the remaining catalpa should have been harvested as well as all 

 defective specimens of the walnut, leaving a probable stand of 400 treeS; 

 which by this time will have attained sufficient size to take care of them- 

 selves. It is likely that in the openings a certain percentage of the 

 catalpa stumps will sprout, and this sprout growth will still further assist 

 the walnut.

Plantation No. 7. — This plantation is situated on the Jvlissouri river 

 bottom. The soil is a ftch black loam, 5 to 6 feet deep. It is fresh, por- 

 ous, and exceedingly fertile. The site is traversed by a small stream, 

 which occasionally overfiows and courses out through the grove, inundat- 

 ing a "good part of it. Water does not stand on the surface more than a 

 day or so. 



The plantation was grown direct from the seed. Cultivation had 

 been given the land for two years previous to planting. The nuts were 

 planted in the fall of 1869. After the ground had been plowed and har- 

 rowed as for corn, single rows, 4 feet apart, were marked off with a
