stove treatment till May, when they are placed in the green¬ 
house again, keeping it rather closer than usual for a day or 
two, and gradually inuring them to the air, as with ordinary 
greenhouse plants. In June I again shift them, this time into 
twelve-sized pots thoroughly drained with potsherds and pebble¬ 
stones, mixing a number of the stones with the soil, which 
should consist of sandy peat, and if it is not naturally so, it 
should be made such, by adding silver sand; and on no pretence 
must the cultivator ever think of sifting the soil, for the rougher 
it is the better. After the shifting is complete, a trellis is fixed 
to the pot on which the plant is trained, and I consider it will 
not require to be again shifted for two or three years, only en¬ 
larging the trellis as the plant may increase in size. By the 
above treatment I find that, in the course of two years, a fine 
compact plant may be obtained, particular attention being paid 
throughout the whole period to preserve it moderately moist.

CULTURE OF IOCHROMA TUBULOSA (HABRO- 
THAMNUS CYANEUS). 
This is a handsome, free-flowering, deciduous greenhouse or 
half-hardy shrub, growing about four feet high. It grows freely 
in an equal mixture of sandy loam and peat; but when the 
plants are young, they should be grown in a richer soil, in order 
to gain size and substance quickly. When they have attained 
a considerable size, they require to be kept rather dry, and to 
be stunted in the pots. A good way to treat the plant is to turn 
it when young into the open border in a very rich soil, about the 
end .of May, to supply it abundantly with moisture during the 
summer, and to take it up about the end of September, pot it, 
keeping it in a close place for a week or two, to recover the 
shift; and then to place it in a rather dry situation, where it is 
secure from frost for the winter. About the middle ol the 
following March cut it back rather freely, and top-dress the soil 
in the pots, but by no means re-pot it; allow it to start in a 
rather cool, but not very dry situation. As it advances, watei 
more freely, and finally keep it rather close and damp to cause
