weeds bear seeds" in the same way, and 

 vast numbers of them are eaten ^by 

 ducks. 



The general appearance of sago pond- 

 weed is well shown by figure 17; note 

 the brush of fine threadlike leaves and 

 the seed clusters as above described. 

 Here also are shown the tender root- 

 stocks with their tubers, delicacies much 

 scught by many ducks. Figure 18 illus- 

 trates the tubers enlarged.

from coast to coast, and as far south 

 as Florida,* Texas, the Mexican Pla- 

 teau, and Lower California, and north to 

 Nova Scotia, Hudson Bay and along the 

 Pacific coast up to latitude 62° north 



Transplanting Pond weeds. 



Much less is known about the trans- 

 planting of pondweeds than of wild rice 

 and wild celery, but it is just as feas- 

 ible, f The Fish Commission stations use 

 pondweeds to some extent in their fish 

 ponds, and no difficulty seems to be en- 

 countered in transplanting them. Mr. 

 Dwight Lydell, of the Michigan State fish 

 hatchery, states that he has succeeded in

 seeds and of whole plants. He further 

 states that the most successful and 

 largest growths have been on bottoms 

 where the mud is about 6 inches deep 

 over sand or clay. By mowing the plants

* The manuals of botany give the ran~e of 

 this plant as south to Florida. We have been 

 able to find definite records only as far as 

 North Carolina. In our map (fig. 19) the 

 northern limit of the plant is extended to Great 

 Slave Lake, on the basis of the probable dis- 

 tribution of an acquatic plant recorded from 

 the Lewes River at 62° north latitude, and 

 rear the mouth of the Severn River, Hudson 

 Bay. 



f Since the above was written Mr. J. B. 

 White, of Waterlily, N. C, has sold and trans- 

 planted thousands of dollars' worth of sago —
