O OME years ago I noticed an apparent radial movement of the ascendincr ^J branches in certain shrubs and small trees, whereby the branches were brought closer to the main stem in the winter, quite independently of the leat-frll, and were separated from It on the approach of spring. After trying in vain to find some account of this movement, and its causes, in the literature accessible to me^ and from various persons informed on such matters, I undertook a study of it, with results which follow. In the autumn of .898 I chose six shrubs and small trees, in the Botanic Uarden of Smith College, which showed the movement and which were isolated from other woody plants. Selecting long slender branches on the north, south, east, and west sides of -ach plant, I made near the top of each, and on the side radial to the plant, small dots with water-proof India ink, the approximate positions of which were marked for convenience by coloured threads.
