Growers of let- FiG. 13. ShowiDg navy bean plants grown from large seeds (left) and from small seeds (right), tuce under glass are sometimes able to raise one more crop during the winter by sowing only the largest seeds than when the seed is sown without sifting. The practice of sifting seeds before planting, and rejecting the smaller ones, should be more generally followed (Fig. 13). 49. The Earlier Germinations from a sample of seed often Form More Vigorous Seedlings than the Later Ones. This is one of Nature's methods for preserving the vigor of plants. The stronger seedlings overtop the later and feebler ones and crowd them out of exist- ence. We should profit by this hint and reject the later plants in the seed-bed. 50. How Deep should Seeds be Planted? We have seen that one object of planting seeds in the soil is to.
