The score card, which has often been used as a guide in selecting

selected from the crib may yield about as much as larger cars. It should be kept « M/HC/ //m/ these figures are based on crib selection, w and that this method is not to be recommended in normal years. This year in order to get corn that will grow it will be necessary to disregard many of the points which have been considered important, If necessary, we must sacrifice everything for strong, vigorous germination. From every section of the state reports have been received which indicate that most of the corn saved for seed is very low in germination. This means that in most cases every ear of seed must be tested, altho if a composite test shows a germination of 95 percent the individual ear test is not very important. This composite test may be made as follows: Go thru the crib and pick out 100 ears which would ordinarily be considered fit for seed; select six kernels from the ears according to the method described later under the rag-doll test, and place them in some sort of a germinator. If, by the above method, a test of 95 percent is obtained (at least 570 kernels showing good germination), further examination of the corn in this respect will be unnecessary. It is probable, however, that very little corn will be acceptable oy the composite test. Therefore, the individual ear test will be found necessary. This means that every ear must be tried for germination. There are numerous methods of applying this individual ear test, and there are many kinds of commercial testers on the market, but homemade devices are as good as those which cost money. Two general types of homemade testers and general suggestions for their management are described below. THE RAG-DOLL TESTER J or the following reasons

Counting the grains is less difficult, because the entire roots can be observed. 7. The rag-doH taster is small, and •' dolls'' can be stored a space.
