National Geographic : 1961 May
I realized that they had been too young to remember much about the terrarium full of carnivorous plants that I had grown in our New York apartment six years before.* This time I had two terrariums, as well as a con servatory no bigger than a doghouse in our garden. We were prepared for both indoor and outdoor observation of the insect eaters. The Author: Senior staff member Paul A. Zahl ably employs camera and typewriter to provide fascinating glimpses into natural history. He is a research associate of Haskins Laboratories and the American Museum of Natural History, New York City. For his most recent NATIONAL GEO GRAPHIC contribution, see "How the Sun Gives Life to the Sea," in the February, 1961, issue. 644 Completing our shipment from North Car olina were plants of several other kinds that trap insects, numerous clumps of mosses and liverworts, and two 50-pound bags of acid soil. These were basic ingredients of a south ern boggy lowland, a few square feet of which we hoped to re-create in a corner of our Washington garden. Though insectivorous plants are unique in being able to eat meat, the leafy types still need sunlight. Accordingly I had made my conservatory lid of transparent plastic and its sides of glass. To ensure a warm and humid climate, I sealed the structure but left one pane adjustable for ventilation. *See "In the Wilds of a City Parlor," by Paul A. Zahl, NATIONAL GEOGRAPHIC, November, 1954.
