222 THE ORCHID REVIEW. [JULY, 1914. 
Ea MANURIAL AID TO ORCHIDS. Fee) 
ITH the exception of the terrestrial Cymbidiums, Calanthes, Phaius, 
\ Peristeria elata, and Zygopetalums, there are few other genera 
which are benefited by direct application of manures, but from personal 
experience I am strongly convinced that if the houses, Cattleya and Warm, 
are damped down with liquid diluted cow manure, about twice a week from 
April to September, very beneficial effects will be derived. The late 
afternoon is the best time, and the paths, staging, and earth under the 
latter should be well damped, taking care, of course, not to allow any 
manure water to touch the plants themselves. 
Cattleyas and their allies, Vanda ccerulea and Phalzenopses, seem to 
delight in manurial aid in this indirect manner, for extraordinary root 
action is thereby brought about, which in itself testifies to vigorous growth. 
Besides being practised in my own collection, I know of some others where 
this method of damping with manure water is carried out, with highly 
satisfactory results, whilst I believe it is extensively performed in American 
Orchid establishments. 
From personal experience I am convinced that the best results are to be 
obtained from the employment of fairly fresh cow-manure water, which 
gives off a large amount of ammonia, which is so beneficial to plant 
development ; guanos and other animal manures not seeming to exert such 
beneficial effects. 
Cool house Orchids do not, however, seem to respond in any Way ‘ 
manurial damping, and I have failed to notice any appreciable difference mn 
plants treated with the Cookson Formula, but for promoting vigorous root 
action in Warm house Orchids, and Cattleyas in particular, there * 
undoubtedly no better stimulant. 
The experience of other readers would be of interest.

A FLOWER of a very beautiful Lzeliocattleya is sent from the collection 
of W. Waters Butler, Esq., Southfield, Edgbaston. It was 4 
chased as L.-c. Marguerite (L. purpurata x C. Mossiz virginalis), and ® 
Mr. Butler points out, the Orchid Stud-Book gives L.-c. Marguerite oa 
hybrid from C. Warscewiczii and L.-c. Schilleriana, whereas the hyb 
from L. purpurata and C. Mossi is L.-c. Canhamiana. It is 1 a
