In spring water, the number of bacteria is relatively small, but in water into which sew- age from cities drain, the number is extremely large. Sometimes bacteria in water contaminated with sewage are disease producing. The soil that has been well cultivated is usually rich in bac- teria. The deeper layers of soil contain few or no bacteria. Where the soil is drv and sandv, there are relativelv few bac- teria; where it is moist and loamy, they are abundant. They are found in great numbers around the bodies of dead animals or in soil that contains decaying roots of 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 Wheat, Frank Merrill; Fitzpatrick, Elizabeth T.
