and worry; also making it possible to accomplish more work in other 
advantageous ways than would be possible without their assistance. 
In turning over houses of plants a few will be sure to be found on the 
sickly side, and these should be removed from the batch and placed by 
themselves, where they can be specially treated. This can often be best 
done by removing them to another house altogether. J have many times: 
found that a plant will recover much more quickly when removed from the 
house in which it went wrong, and in a place where the conditions in some 
way differ. We oftentimes find a change of air and conditions beneficial 
to us when feeling seedy, and I believe it is equally beneficial to a sickly 
plant, but with all such plants vigilance is doubly necessary. 
My experience in recovering sickly plants is to place them as far as pos- 
sible in a house that is of a very humid nature, so that the plant has much 
constant humidity with very little direct watering. In some cases, especially 
with plants that under ordinary conditions are grown very wet, putting 
them for a time in a somewhat dry house will cause fresh activity. It is 
impossible to give any certain way of recovering a sickly plant, and what 
may prove a cure to one Cattleya may have no effect on another, and after 
one way has been tried for a time if no improvement is apparent try another. 
It isa thing we shall always have to meet as long as Orchids are grown, 
and so long as we think it is possible to find a cure, and not to think that 
it must die, I believe we shall in most cases prevent the great losses that 
have been so pronounced in the Orchid family. With Orchids, as with all 
other kinds of plant life, some must from time to time go wrong, but pro- 
pagation and the cutting away of back portions will to a very large extent 
prevent loss in anything like the same number, wherever this system 1s 
Systematically carried out. 
ODONTOGLOSSUM SEEDLINGS.—It is interesting to hear of further success 
in Odontoglossum raising. The collection of J. H. Grogan, Esq., Slaney 
Park, Baltinglass, now contains a nice little family of Odontoglossum 
seedlings, and about 320 have been pricked off from one cross, with others to 
come. Mr. Grogan considers them very easy to handle when once you have 
got them. Since Christmas last he has been trying the ——— of not 
letting the temperature of the Odontoglossum house go below 50° if he a 
possibly avoid it, and he considers the improvement from this increase © 
temperature to be most marked. Extremes of temperature and ssa 
approaching a dry atmosphere in hot weather seem to be the points to e 
specially guarded against, and at such periods constant erention oe : 
shading and damping down are imperative. It is gratifying to a t 
these beautiful plants are now being raised successfully in so many differe 
collections.
