Excerpt from The Health Bulletin, 1944, Vol. 59 Another most helpful gadget to the plant chemist, and one which interests visitors, is the simple table located in the laboratory. Water from various points throughout the process of treatment is brought to the table by the simple snap of a switch. These samples from five different places - namely, raw water, treated water, settled water, filtered water, and finished water - run through five glass jars. At this point, a visual comparison can be made of the water. Also, samples for daily tests may be collected here.
