Plantation No. 7. This plantation is situated on the Missouri River 

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

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

 stream, which occasionally overflows and courses out thru the grove, 

 inundating 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 harrowed as for corn, single rows, 4 feet apart, were marked off 

 with a common marker. Furrows were then run 8 feet apart at right 

 angles to the marks. The nuts were dropt at the intersection of 

 the furrows with the marks, thus giving a spacing of 4 feet by 8 feet. 

 One nut was planted at a place, making 1,360 nuts per acre. It 

 required 25 bushels (" shucks" on) to plant the 12i acres. They were 

 purchased from the Indians at 25 cents per bushel. After the nuts 

 were dropt, they were covered by filling the furrows with a harrow. 

 This covered them rather too deep, so that only about two-thirds of 

 the number came up the first year.
