Propagation and Culture. All these plants may be raised by 
setting cuttings, made at a joint, five or six inches long, after being- 
rubbed in sand and laid on the shelf a few days to have the wounds 
healed over, in the summer about June, in small pots filled with 
light, dry, sandy mould, with some rubbish at the bottoms, such as 
that constituted of a fourth part of screened lime rubbish, the same 
proportion of sea-sand, and one-half of light, fresh, vegetable earth, 
well mixed and blended together by frequent turning over, plunging 
them in the bark hot-bed, giving suitable shade in the hot sunny 
weather, and a little water once or twice a week, as there may be 
occasion. When the plants have stricken root, they should have air 
admitted quite freely while in that situation, or be removed into the 
stove to be hardened before winter. 
They must afterwards be allowed larger pots once a year as they 
advance in growth, and be frequently refreshed with water in the 
summer season, but only very sparingly in the winter. Most of 
these sorts are capable of being kept on the shelves of hot-houses, 
and some of them, such as the sixth, seventh, and eighth sorts, in a 
dry, airy green-house, or glass-case, during the winter season, care 
being taken to guard them against the frost, and in the summer they 
may be set out in the open air. 
The fifth species stands in need of support to prevent the weight 
of the branches forcing it upon the pots; and by such management 
they will rise four or five feet in height, producing numerous side 
branches. The ninth sort requires little or no care when once intro- 
duced, except keeping the young plants clean, as it will be continued 
by its scattering the seeds. The whole of these varieties, except the 
last, afford variety in hot and green-house collections, and that in 
the borders of pleasure-grounds. 
The properties of EuphorhiacecB are so important, that I do not 
think I should fulfil the object of this work, if I did not, in addition 
to the foregoing general view of the order, add a detail list of the 
qualities of the most important species named by writers — some o.
