270 THE NURSERY. [March. 
season; but, if the berries are kept dry till spring, the greater 
number of them will not grow till the next year. They should be 
covered about an inch deep. 
Maples. 
The Acer argenteum, or silvery leaved, and ^cer ruhrum, or 
scarlet maples, perfect their seeds in May, and should be sown im- 
mediately after having been collected; they will vegetate directly, 
and produce fine plants the first season, if kept free from weeds. 
The seeds of the former do not keep well till spring, but those of 
the latter will. 
The sugar, Canada, ash-leaved, Pennsylvania, and mountain 
maples, and also the ^cer majus, or sycamore, maybe sown either 
in autumn or March, and will succeed well in either season: if 
sown in autumn, cover them about three quarters of an inch deep; 
if in spring, half an inch will be sufficient. When about a foot 
high in the seed beds, plant them early in spring into nursery rows, 
at proper distances. 
Catalpa, Sweet-gum, Papaw, and Persimmon. 
The Bignonia catalpa will grow freely from seed, which is to be 
preserved in the siliques or pods till March, and then sown; or it 
may be propagated either by layers or suckers. 
The Liquidamber styraclflua, or maple-leaved sweet-gum, grows 
freely from seed sown early in spring. 
The Jinnona triloba, or common papaw, is a hardy plant, and 
may be propagated by sowing the seed about an inch deep, either 
in October, November, or March. 
The Diospyros virginiana, persimmon, or American date plum, 
is best cultivated from seed sown in autumn, soon after ripe, or in 
March; if kept up till spring some of them will not vegetate till the 
second year after sowing. 
Chestnuts, Walnuts, Hickories, and Oaks. 
About the middle of this month plant the nuts of the European 
and American eatable chestnuts, also of the horse chestnut, and 
likewise of the different varieties of walnuts and hickories, which 
you wish to propagate. All the above kinds should be sown in 
drills, first throwing the nuts into a tub of water, and rejecting such 
of them as swim, covering them with light rich mould about two 
inches deep. The drills may be three feet asunder, and the nuts 
planted about six or eight inches from one another in the rows. 
The different varieties of oak succeed best when sown imme- 
diately after being ripe; but in that case they have to encounter the 
depredations of mice, squirrels, &c. to avoid which, they may be 
be kept in earth or sand till this time; but as most of them will be 
sprouted, you are to take them carefully up without breaking the 
radicles and plant them in drills two feet asunder, covering the
