FOREST TREES. 101 
In spring, they may be planted in ground marked 
out in rows, four feet apart. ‘The Black Walnut is 
inclined to throw out heavy side branches, and form 
a low, spreading top. It must, therefore, be thickly . 
grown to produce tall timber. If seed be scarce, or 
if it is an object to make it go as far as possible, plant , 
nuts eight feet apart in every other row, and plant 
the intermediate rows and spaces with corn or 
potatoes, After two years, the Walnuts will be well- 
established; the spaces should then be filled with 
Silver Maples, slips of White Willow, or some other 
fast-growing tree, easily and cheaply obtained, placed 
two feet apart. These are to be thinned out as occa- 
sion requires. The Black Walnut trees, at eight feet 
apart, will grow to such a size as to be of value for 
many purposes; but before becoming large enough 
for saw-logs, they must be thinned to two or three 
times that distance. Someattention should be given 
to pruning the young trees while small. The leading 
shoot will sometimes fork, or a side shoot of too 
vigorous growth be thrown out. These should be 
shortened, or cut out entirely. 
The Black Walnut is a bad neighbor to many other 
trees, and should, as far as possible, be grown by 
itself. It is unfit for a screen to an orchard. Apple 
trees will not live long in its neighborhood, and the 
same is probably true of some, if not all, other fruit 
trees. 
Some persons have thought it necessary to crack 
the nuts before planting them. This is altogether 
needless, even if it were not true that it is scarcely
