The soil in which seeds grow out of doors is always moist; most kinds germinate best in earth not nearly saturated with moisture. 8. Relation of the Air Supply to Germination.— If we wish to see how soaked seeds will behave with hardly any air supply, it is necessary to place them in a bottle arranged ' For the exact regulation of the temperatures a thermostat (see Appendix II) is desirable. If one is available, a maximum temperature of 100° or over should be 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 Bergen, Joseph Y.
