It is therefore neces-sary to supply inoculation before a good growth can be secured. In California seeding may be done at any time during the summer,or in the fall before the winter rains begin. In the Southern Statessummer seeding is not advisable, on account of rains, and seed shouldbe sown in the early fall, so that it will start and continue growthduring winter. About the first of September is perhaps the best timefor seeding in most sections. When bur clover is once seeded itpersists indefinitely. Species with spiny burs, having the advantageof this means of distribution, are perhaps more persistent than specieswith smooth burs. Spiny burs are less readily eaten by animals.Thus protected, man)r of them drop or are knocked from the plants,are trampled into the ground, and thus reseed themselves.
