Mr. Hunnewell has gathered together a large number of these, especially the freer blooming and more serviceable sorts. There are large pans of Cypripedium Doyanum, a handsome leaved as well as a pretty flowering plant, but more decided in the variegation of its foliage, is a companion specimen of C. Lawrenceanum. Several other species are in bloom, and on one plant of insigne I counted forty-three flowers. A very fine lot of Phalaenopsis grandiflora, amabilis and Schilleriana were growing in a dark corner, and far away from the glass. The pots containing them were set upon empty pots that were standing in saucers filled with water; these act as evaporating pans, and at the same time prevent the approach of wood-lice, cockroaches, slugs and other insects that might injure the flower-spikes or roots. Mr. Harris expressed himself as averse to growing the mass of orchids up close to the glass, and quoted his Phalaenopsis as an example of shadier treatment. We also remembered the splendid Mas devalleas at Albany, and which were the biggest and thriftiest specimens I ever saw, and they were grown right by the floor of a high green-house with apparently as little concern as if they were palms or club-mosses. But notwithstanding these exceptional examples, I am in favor of nearer the glass.

The Dendrobiunis were gathered together in a cool house to ripen their shoots. D. Goldii with terminal spikes of purple flowers, and Formosum giganteum, white and yellow, were beautifully in bloom. And in a little basket overhead I beheld D. Brymerianum with two shoots about eight inches and thirteen inches long - ten guineas worth; and near by the almost equally choice Laelia anceps alba with four flowers. It would take too much space to wander through the host of Cattleyas, Calanthes, Odontoglossums, Oncidiums, and other genera, but their uncommon thrift and vigor are well worth critical examination.
