In autumn some plants, especially in woodlands, have seeds that cling-to animals' hair and to woolly clothing as you walk through them. Collect burdock burs, beggar lice, sticktights, Spanish needles, etc., in cellophane bags. Examine each under a magnifying glass and mount a specimen on cardboard, identifying it by name, name of parent plant, and an enlargement of what enables it to steal a ride. Count the seeds in burdock burs. This and other autumn projects are described in our bulletin No. 465, one of six dealing wholly or in part with seed dispersal.
