volume of his Miscellanea, under the name of Boletus Laricis. It is also called Agaricus purgans: 
and is used in the northern countries as an emetic in. intermitting fevers. The Funguses dye the 
hair of the rein deer with this Fungus and the roots of Gallium, of a very deep red colour; whence 
perhaps it may be of some use in dyeing. The body of this Fungus is saponaceous, and is used by 
the women in some parts of Siberia, to Wash themselves, and even their linen.* It was celebrated 
formerly, but is now deservedly fallen into total disuse, as a medicine. 
From the Pines properly so called, with the Cedar and Larches their allies, we discriminate 
the Firs, which are distinguished from them by having the leaves single and distinct at the base; 
whereas the former have them two or more, or even in bundles, from the same sheath;

CULTURE. 
The Pistacia-nut tree is propagated by the nuts, obtained from abroad, planted in pots filled 
with light kitchen-garden earth, and plunged into a moderate hot-bed: when the plants appear, 
admit a large share of air to them, to prevent their drawing up weak; and by degrees harden them 
to bear the open air, to which expose them the beginning of June till autumn, when they should 
be placed under a hot-bed frame to screen them from the frost in winter, for while they are young, 
they are too tender to live through the winter in England without protection, but they should always 
be exposed to the air in mild weather; these, plants shed their leaves in autumn, and therefore 
should not have much wet in winter; and in the spring, before the plants begin to shoot, they must 
be transplanted each into a separate small pot; and if they are plunged into a very moderate hot¬ 
bed, it will forward their putting out new roots; but as soon as they begin to shoot, they must be 
gradually hardened, and placed abroad again; these plants may be kept in pots three or four years 
till they have got strength, during which time they should be sheltered in winter; and afterwards 
they may be turned out of the pots, and planted in the full ground, some against high walls to a 
warm aspect, and others in a sheltered situation, where they will bear the cold of our ordinary win¬ 
ters very well, but in severe frosts they are often destroyed. The trees flower and produce fruit in 
England, but the summers are not warm enough to ripen the nuts. 
The Turpentine tree may be treated in the same manner, and is as hardy. The plants of this 
sort are generally propagated by laying down their young branches, which, if properly managed, 
will put out roots in one year, and may then be cut off from the old plants, and each transplanted 
into separate small pots. These must be sheltered in winter,. and in summer placed abroad in a 
sheltered situation, and treated in the same way as other hardy kinds of green-house plants. It
