The apparatus shown has proved very useful for the purpose of taking notes on lectures or augmented by slide projection in a darkened room. The parts required are easily obtained in a "ten-cent" store and consist of (1) a large paper clip, (2) a broom holder, (3) a small caliber 1/4 in. (0.64 cm.) nut and bolt, and (4) a flashlight. Owing to the bulkiness of the apparatus when assembled, a nut with a slot wide enough for use of a dime (for tighening or loosening) or a wing nut should be used to enable the parts to be assembled when needed. The separate parts are easily carried in a coat pocket without being too cumbersome.
