‘quires. Acorns and nuts may be planted one foot 
apart; trees from the seed-bed two feet. When grown 
only for other purposes—for fuel, fruit, protection, 
etc., the distance may be varied to suit the object. 
Where hillsides and slopes, not too steep to plough 
but likely to wash, are to be planted, it will be best 
to adopt the practice of cotton growers on uneven 
lands in the Southern States, there called circling. 
The ground is ploughed horizontally and the rows 
marked in the same direction, making curves where 
necessary, to correspond with the surface of the slope, 
and keeping all parts of each row as nearly as possi- 
ble on the same level. By this management the dan- 
ger of injury from washing by heavy rains is greatly 
lessened. 
The sides of ravines and river bluffs, too steep for 
the use of the plough, may be planted with acorns, 
nuts or young trees, with the spade or garden-trowel. 
The European Larch is well suited to such localities. 
The vegetation in such situations is usually thin, and 
the turf not compact, and young trees will thrive 
there without cultivation better than on level lands. 
Land for seed-beds should be deeply ploughed, and 
the soil well pulverized. If poor, itshould be enriched 
‘with well-rotted manure. The seeds may be sown in 
narrow drills, twelve or fifteen inches apart, and cov- 
ered from half an inch to one inch deep, according 
to size. If the ground be somewhat dry, a hand 
roller should be passed over it after sowing. It is 
best to sow as early in the spring as the ground can 
be got in good condition. Some seeds vegetate at a
