CULTURE. In arboriculture, as in landscape planting, 
some of the most ornamental and picturesque of trees 
are to be found amongst the Pines, while other species 
are greatly valued as nurses for more tender trees, for 
forming screens, &. So various are the soils and situa- 
tions in which the different species occur in their native 
countries, that there is scarcely a spot for which one or 
other kind is not suitable; thus, the Scotch or Wild 
Pine grows on the bleakest hills; Pinus Pinaster 
flonrishes in shallow sands near the sea-shore; P. rigida 
attains its greatest perfection amidst the Cedar swamps 
of Virginia; P. ponderosa grows in the arid plains of 
Utah, where no other vegetation exists; and the Scrub 
Pine (P. Banksiana) straggles over the rocks in the cold 
“side. If the latter plan be adopted, the ground should

be made very fine, and the seeds sown in March or 
April, when the ground is in good condition. After 
sowing, pat the bed with the back of a spade, or pass 
a light roller over it, and then cover lightly. ‘The smaller- 
seeded kinds only require a thickness of şin, or even 
less, of sandy loam over them; the larger ones, tin. at 
most. If practicable, shade the beds, and keep them 
watered, until the young plants are sufficiently developed 
to bear full exposure. The following season, the seed- 
lings should be placed in nursery lines, where they 
should not be allowed to remain more than two years 
without being again transplanted, or placed in the posi- 
tions they are intended to occupy permanently. Probably, 
the best results would be attained were the seeds sown 
(and the seedlings not wanted thinned out) in the places 
where the trees were required to grow, This would, of 
course, involve much extra care and expense at first, 
but there can scarcely be a doubt that, to a great 
extent, the trouble would be repaid by the more rapid 
growth of the plants. The gold and silver variegated 
forms, those of a pyramidal habit, as well as the small, 
dense, cushion-like sports, must be increased by grafting 
on seedling plants of their respective types. 
All the species described are hardy, except where 
is unneces- 
that, so far as is yet known, are peculiar to itself, e.g., 
Peziza Wilikommii on Larch, Peridermium elatinum on 
Silver Fir, &. Among the Fungi more hurtful to 
Conifere, and especially to Firs of the genus Pinus, are 
the following: Several species of Polyporus (which 
see) live on the trunks of various Conifers, destroying 
the wood, and causing it to become soft and rotten. 
The tree is apt to break across at the part on which 
any kind of Polyporus has existed for some time.

Rot, which causes the death of the tree. — 
chiefly at the roots, and an attack is frequently 
suspected until the tree becomes pale green and dies. 
The roots are then found to be overgrown with the 
spreads gradually from a centre, destroying the trees 
within a progressively larger area, and without visible 
canse, as Fungus passes from root to root in the 
soil. ; 
The genus Trametes is nearly allied to Polyporus in 
structure and mode of life, and differs only in the 
former having the spore- bearing tubes imbedded in 
a substance similar to that in the pileus, while in the 
One species, T. Pini (see Fig. 164), grows on living Fir-trees 
(more rarely on other Conifers), in which it also causes a
