Many other species have grown on the waste-heap, but have not 

 attained sufficient maturity to afford me any help to their identifica- 

 tion ; probably an expert could have recognized many of them. 



Another species that has evidently come to stay is Chenopodium 

 foetidum, Schrad. Its introduction may have been through the 

 medium of the wool-waste, or in grass-seed. In the fall of 1900, the 

 intervale where it has occurred was " broken up " and seeded ; during 

 the winter and spring of 1901, several heavy rains caused the river 

 to overflow the peninsula formed by the lower end of the intervale, 

 the top soil of which was scraped away by the ice, which was driven 

 across it, instead of being carried around in the channel of the river. 

 Hardly anything besides Barbarea vulgaris, R. Br., and Asckpias 

 Cornuti, Dec, appeared that season, the ground lying fallow through- 

 out the year. In the spring of 1902, the field was plowed, re- 

 manured (by which means the seed may have been brought in, the 

 dressing coming partly from a stable where baled hay had been fed) 

 and planted to potatoes and corn. In August and September of this 

 year, I found a considerable quantity of the Chenopodium among the 

 potatoes, but none among the corn. In 1903, the field was planted to 

 the same crops, and the weed was abundant in all parts of the field. 

 I would suggest that some appreciative botanist change the specific 

 name from foetiditm to fragrans, as I consider the odor pleasing. 



Newly seeded fields, especially those seeded without grain in the 

 fall, have always been among my favorite hunting grounds. In one, 

 about ten years ago, I found Berteroa incana, DC, Camelina micro- 

 carpa, Andrz., Sisymbrium altissimutn, L., Thiaspi arvctise, L., Viola 

 arvensis, Murr., Silene Cucubalus, Wibel., S. noctiflora, L., S. dicho- 

 to?na, Ehrh., Stellaria graminea, L., Medicago saiiva, L., Melilotus 

 alba, Desr., M. officinalis, Lam. Heliopsis scabra, Dunal., Echium 

 vulgare, L., Narcissus poeticus^ L., and Or?iithogalum ufubellatum, L., 

 the last two being, of course, garden escapes. The greater number 

 of these have fallen asleep, but Heliopsis, Narcissus and Ornitho- 

 galum remain unto this day.
