iore, I remarked with astonishment an _Onc. fuscatum_, of which the lip was scarlet-crimson and the other tints bright to match. That collection is admirably grown, but orchids are still scarce in Italy. The Society did not know what a prize it had secured by chance.
The genus Oncidium has, perhaps, more examples of a startling combination in hues than any other--but one must speak thoughtfully and cautiously upon such points.
I have not to deal with culture, but one hint may be given. Gardeners who have a miscellaneous collection to look after, often set themselves against an experiment in orchid-growing because these plants suffer terribly from green-fly and other pests, and will not bear "smoking." To keep them clean and healthy by washing demands labour for which they have no time. This is a very reasonable objection. But though the smoke of tobacco is actual ruination, no plant whatever suffers from the steam thereof. An ingenious Frenchman has invented and patented in England lately a machine called the Thanatophore, which I confidently recommend. It can be obtained from Messrs. B.S. Williams, of Upper Holloway. The Thanatophore destroys every insect within reach of its vapour, excepting, curiously enough, scaly-bug, which, however, does not persecute cool orchids much. The machine may be obtained in different sizes through any good ironmonger.
To sum up: these plants ask nothing in return for the measureless enjoyment they give but light, shade from the summer sun, protection from the winter frost, moisture--and brains.

I am allowed to print a letter which bears upon several points to which I have alluded. It is not cheerful reading for the enthusiast. He will be apt to cry, "Would that the difficulties and perils were infinitely graver--so grave that the collecting grounds might have a rest for twenty years!"

DEAR SIR,
I have received your two letters asking for Cattleya Lawrenceana, Pancratium Guianense
