one. I have before now tried some especially careful treatment for it, 
but it has invariably gone off the quicker for my pains. 
Two pretty little Oncidiums are now in bloom, namely O. ornitho- 
rhynchum and O. incurvum. They both grow fairly well in the Coolest 
house, but the Intermediate one is really the best for them. They enjoy 
a lengthy period of rest when blooming is past. Such Oncidiums as O. 
Forbesii, O. crispum, and O. varicosum, which have completed their new 
pseudobulbs and are sending up flower spikes, do well if now moved from 
their shady summer-growing quarters and placed in a house similar to that 
where Dendrobes, &c., are resting. They then get much light and air, which 
of course ripens the somewhat sappy new growth, and this takes place 
withcut interfering in the least with the growth of the flower spikes, in fact, 
the latter come more sturdy and strong in consequence. It is impossible 
to give these Oncidiums the necessary amount of resting or ripening if the 
process is left over until their blooming season is past, because that time 
is frequently as late as November, and by then, of course, it is too late. 
Habenaria carnea and H. militaris, two pretty little terrestrial growing 
species, are very conspicuous now, and are well worth growing; after 
blooming is over yery little water is required, as they are deciduous. They 
should be given a winter position on a shelf, or some such place, in a warm 
or intermediate temperature, and watered at long intervals and with extreme 
care when at rest throughout the winter, or the tubers will decay. A 
number of tubers in one large pot give not nearly so much satisfaction as 
when grown singly, or from one to three, in small but rather deep pots, 
The compost should consist of peat crumbled up small, with a liberal 
addition of sharp sand and finely broken crocks well mixed up together. 
Two or three small crocks for drainage is sufficient, as the tubers grow to a 
great length. Early in March signs of renewed growth will appear from 
the apex, when they should be repotted. 
Dendrobium formosum, D. Phalenopsis, and allied autumn-blooming 
kinds, are now fast approaching completion of growth, and sending up their 
bloom spikes. They are well known heat-loving kinds, and must have the 
warmth of the East Indian house to be well grown. They, will still require 
liberal waterings at the root, and in another month or so will repay all the 
trouble bestowed by a grand display of flowers. It is not absolutely 
impossible to grow these heat-loving kinds in intermediate temperature, as 
also D. Johnsoniz and D. atroviolaceum, but they do not grow so freely nor 
make such long pseudobulbs, though what they do make are perfectly 
sound and vigorous. In fact what I have seen so grown are perfectly free 
from all kinds of spot and disease, and have the appearance of lasting and 
continuing to grow, if more slowly, which is not always the case with them 
when grown in great heat, and this makes me come to the conclusion that
