If the collection is large, a card index will be of great assistance in finding the specimens. Germination Tests, âThe seeds used in germination tests must be taken indiscriminately from pure seed which has been thoroughly mixed for that purpose. The selection of plump, nice-looking .seeds for these tests, as frequently practiced, impairs the authenticity of the result. Tests may be conducted in the laboratory between damp cloths or bluttcrs, or in porous saucers, or in sand or soil in n -r. â . which are known to ger- "uUl be tested in a greenhouse ⢠ry.

This may be remedied to a certain extent by placing narrow strips of glass between the folds, but main reliance in such cases should be placed upon soil tests. All tests are to be made in duplicate, using two lots of 100 seeds each of peas, beans, corn, cu
