to Scotts Valley, California, and in 1947, opened an horticultural attraction called the Tree Circus. Erlandson lived from 1884 to 1964; training more than 70 trees during his lifetime. He considered his methods trade secrets and when asked how he made his trees do this, he would only reply, "I talk to them." His work appeared in the column of Ripley's Believe It or Not! twelve times. 24 trees from his original garden have survived transplanting to their permanent home at Gilroy Gardens in Gilroy, California. His Telephone Booth Tree is on permanent display at the American Visionary Art Museum in Baltimore, Maryland and his Birch Loop tree is on permanent display at the Museum of Art and History in Santa Cruz, California. Both of these are preserved dead specimens. Arthur Wiechula Arthur Wiechula was a German landscape engineer who lived from 1868 to 1941. In 1926, he published Wachsende Häuser aus lebenden Bäumen entstehend (Developing Houses from Living Trees) in German. In it, he gave detailed illustrated descriptions of houses grown from trees and described simple building techniques involving guided grafting together of live branches; including a system of v-shaped lateral cuts used to bend and curve individual trunks and branches in the direction of a design, with reaction wood soon closing the wounds to hold the curves. He proposed growing wood so that it constituted walls during growth, thereby enabling the use of young wood for building. Weichula never built a living home, but he grew a 394' wall of Canadian poplars to help keep the snow off of a section of train tracks. Dan Ladd Dan Ladd is a Northampton, Massachusetts based American artist who works with trees and gourds. He began experimenting with glass, china, and metal inclusions in trees in 1977 in Vermont and started planting trees for Extreme Nature in 1978. He became inspired by inosculation he noticed in nature and by the growth of tree trunks around man-made objects such as fences and idle farm equipment. He shapes and grafts trees, including their fruits and their roots, into architectural and geometric forms. Ladd calls human-initiated inosculation 'pleaching' and calls his own work 'tree sculpture'. Ladd binds a variety of objects to trees, for live wood to grow around and be incorporated, including teacups, bicycle wheels, headstones, steel spheres, water piping, and electrical conduit. He guides roots into shapes, such as stairs, using above-ground
