During the winter months the thermometer should register from 60° F. to 65° F. by night and about 70° F. by day. With sun heat a few degrees more will do no harm. On the approach of spring the temperature should be advanced to prepare the plants for summer heat, and ac- cordingly decreased on the approach of fall. About the middle of February a light shading will be necessary to prevent excessive heat and sunburn, with heavier shad- ing toward midsummer, this to be gradually removed in the fall and entirely dispensed with during the winter. The greater part of the species grow best in pots in a compost of two parts peat-fiber to one part chopped liv- ing sphagnum moss, one-half of the pot room being de- voted to clean drainage. The compost should be pressed in rather firmly about the roots, and the surface left convex to discard surplus water and to insure the base of the plant against decay during dull weather. A few heads of living moss pricked in over the surface will give a neat appearance. Cypripedium insigne and kindred species should have one-third chopped sod added to the above mixture {see note on cult
