an average height of about two feet, and propagates itself from 

 both bulbs, runners and seeds. In setting out these plants, use a 

 trowel and set them firmly in the mud, about six feet apart. Set 

 at this distance, it will require one thousand plants to the acre. 



It is important that seeds, plants, and bulbs of these and all 

 other aquatic plants, be kept moist until the time for planting 

 arrives. The seed of wild rice and wild celery may be carried 

 through the winter in cold storage in barrels of water kept at a 

 temperature slightly above the freezing point. Wild celery plants 

 and wapato bulbs should be "heeled in" in moist earth, and kept 

 well watered until ready to be transplanted. 



Wild Millet (Echinochloa Crus-Gal/i) is also well worth consid- 

 eration as a food-plant for wild ducks. This species is not like the 

 preceding, strictly aquatic. Neither do the seeds require to be kept 

 moist until the time of sowing. It is a rank growing grass, vary- 

 ing in height from one to six feet, according to the character of 

 the soil. 



It should be sown from May first to July, in moist heavy soil, 

 along the edge of marsh, lake or pond, and is said to grow in 

 water a foot in depth. 



The seeds shatter from the large fruiting heads to the ground 

 or water, and the plant will reseed itself. Sow at the rate of fifty 

 pounds to the acre. Many species of wild ducks seek their food 

 on the shore as well as in the water, and this plant is one that 

 furnishes these waterfowl with a land food supply. In passing it 

 might be well to mention the fact that Wood Ducks frequent the 

 vicinity of water-oaks in the autumn, the acorns of which they are 

 very fond. 



To those who may be interested in the further study of wild 

 duck foods, attention is called to the following bulletins issued by 

 the United States Department of Agriculture: "Three Import- 

 ant Wild Duck Foods," Bureau of Biological Survey, No. 31; 

 "Five Important Wild Duck Foods, "Bureau of Biological Survey, 

 No. 57; "Eleven Important Wild Duck Foods,' ' Bulletin of the 

 United States Department of Agriculture, No. 205. These pub- 

 lications may be obtained by addressing the United States Bureau 

 of Biological Survey, Washington, D. C.
