 "We have scattering seedling pecans growing on all of the different types of soils in the state of Louisiana; and while they do not grow so large on the poor hill lands, some of them bear good quantities of nuts."

Testimony as to the upland growth of the pecan east of the Mississippi River can be piled up almost indefinitely.

A great many of the large trees of the North and East, including most of those previously mentioned, are on upland.

In my experimental nursery on a slope of the Blue Ridge Mountains, fifteen miles southwest of Harpers Ferry, two vatieties of pecans (Busscron and Buttcrick) bore well-developed nuts three years after they were grafted. They did this in the cool season of 1926. Soil is one thing, but frost is another. Late frosts are as deadly to pecans as to most other blooming plants. Hence the following advice from one of the pioneer pecan experimenters, Mr. T. P. Littlepage, who has an orchard between Washington. D. C, and Baltimore, "Under no circumstances should northern nut trees be set on low land. The northern pecan on my farm is just as subject to frost as peaches or more so. As a result I do not think I will have a peck of pecans this year on thirty acres. But I am equally sure that were they on nice high peach land, the average successful crops would be equal to those of peaches or apples."
