Among the many striking instances of horticultural skill, exhibited at the last meeting at Chiswiek, nothing attracted more attention than a terrestrial Orchid, well known to amateurs under the title of Dua grandifiora. From among some grassy leaves this gorgeous plant sends up a stem bearing erect some three or four flowers, each as large as a lady's hand, and of the richest crimson, melting into yellow.

It occurs at the Gape of Good Hope, and in no other part of the world. In that colony its favorite haunt is Table Mountain, where, according to Dr. Harevey, it is so common that every stream is literally bordered with it in March. Sir John Herschel tells us that the temperature of the situation where it occurs is occasionally as low as 31 1/2°, and also occasionally as high as 96½°. It lives on the borders of pools of standing water, the drainage of the boggy slopes of the mountain, in which its roots are immersed. These are dry or nearly so in summer. But it is frequently involved in the dense mists of the clouds, which, even in the hottest months, often prevail for a week or fortnight at a time.

These facts, and his own observations, appear to have suggested to Mr. LEach that skilful course of treatment which has led him to such entire success. How he proceeds we learn from a letter with which he has favored us:

"I would say that my success in growing it has, I think, resulted simply from treating it as a greenhouse plant, and not drying it off for rest, as is usually done with Cape bulbs. I have not yet been able to perceive that my plant has ever been perfectly at rest; leaves seem either to be lengthening or offsets coming up- - it was this peculiarity which determined me upon continuing to give it water all the year round - moderately, of course, during winter, while the thermometer was ranging between 35° and 45°, and freely during the other parts of the year.

"I suspect that, in its native habitats, though long continued heat and drouth may cause all foliage to die down, the roots, nevertheleas, in the ravines where I understand it grows, remain continually moist With me, however, a change of habit seems to take place, and the offsets of last autumn and winter become the flowering plants, not of this, but of next year; while those now in flower will die down, leaving an abundance of plants, scarcely half grown, and followed soon afterward by fresh offsets.

Rough fibrous peat is the soil I use, with a good portion of silver sand; good drainage, of course - and, from the results I have obtained, I see no reason why this very beautiful species should not be found in the greenhouses of every one disposed to bestow the same care upon it which he gives to his Geraniums, and such like plants".

In this belief we concur, provided always a master's eye is present, to insure the plant against that neglect or forgetful ness which kill more fine plants in a year than merely bad cultivation in a century. - Gardsners' Chronicle.
