As the desired end of all our endeavors in the culture of plants is to obtain a knowledge of their requirements, that resulting from practical experience is of the most value. Referring to the above orchids I would state that I find Stan-hopea Wardii as amenable to cool treatment as the Mexican species, and have bloomed it as easily and as well the past summer, notwithstanding it comes from Venezuela and is assigned to the intermediate house by most authors. The beautifully spotted, golden blossoms, are delightfully fragrant, though not more lasting than those of the other species. I can now say with certainty that culture out of doors, in a partially-shaded locality from May to October is in this latitude (Virginia), an assured success, and Stanhopeas look healthier and appear to do better than under glass. They have repaid with a profusion of bloom the past summer, several plants having three spikes of flowers and on one spike ten blossoms.

As far as tested the same out-of-door treatment succeeds well for Epidendrums also, and an enthusiastic grower of orchids in Maryland is firmly of the opinion that all the cool orchids may be successfully grown in summer, under the shade of trees, and thrive better than in a greenhouse not kept sufficiently cool.

It was not my intention to include E. bicornu turn among those needing cool treatment, well knowing it is not so regarded, though as printed my language may bear that construction. I have had little experience with it. The statement I made being all I can say practically, but a friend grows it and blooms it successfully in a cool house with no extra amount of heat. He gives it a warmer place than other Epidendrums, and though it is usually considered difficult to grow and flower he does not so regard it. I have grown and flowered small plants of E dichromum in a cool house, but he has grown large plants to perfection and with strong spikes of large flowers. He does not consider it a "miffy" orchid, but to get the full effect the plant must be large; then it is grand and it remains long in bloom.

Epidendrum vitellinum majus is a very satisfactory plant for the amateur. One that was in bloom four months from last Christmas has now a fine spike of twelve to fifteen flowers and buds of the well-known and brilliant orange-scarlet. I grow it best on a block, with a little moss, but it will succeed in a pot or pan near the glass in sphagnum. I shall try A. J. E's. (page 233) method of growing on the bare wood, and doubt not it will succeed as well as some other Epidendrums, and several Laelias and Cattleyas. Coming from a cold region it seems to require much moisture at the roots. Epidendrum nem-orale majus succeeds well and blooms profusely under the same treatment with sphagnum upon a block.

If opportunity offers I will send you a few words regarding Oncidiums, many of which are very easy to grow well, and are very dainty and pretty.
