This device is for use in connection with electric or water-power air pump. It is capable of a number of variations, once the principle is understood. There are two columns of water in the tubes, one solid and one punctuated by air bubbles, thereby making it the lighter. This causes it to rise and therefore establish circulation as long as air is supplied. A ^-inch diameter glass surgical drain is shown at A. This should contain about eight small openings and be suspended two inches above the sand. This is connected by a short piece of rubber tubing to the rest of the system, which is of glass tubing from 5-16- to ^-inch inside diameter. The dark sections represent rubber joints, making the system more flexible, less liable to Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Innes, William T.
