Compare garden slugs with marine or fresh-water snails, which they may be seen to resemble, except in respect to the rudimentary shell. These slugs are often as destructive in gardens as any in- sect, and, 1)eing nocturnal, are little known. Collect the eggs (translucent, yellowish, about the size of buckshot, in masses of thirty or more, found in damp }>laces nnder boards) and keep them in a glass jar or aquarium to watch their development. If the life history of these pests were better known, we might control them more effec- tively abont our gardens and greenhouses. In connection with other field work, make a collection of common marine, fresh-water, and terrestrial gastroi>ods. Keep them in suitable acpiaria or \ i\aria, to study habits and foods.
