Other weeds, arranged in the order of their importance, were — 



1. Chenopodium album L. 9. Acalypha Virginiea L. 



2. Plantago Rugelii L. 10. Amarantus retroflexus L.

 were equally conspicuous the present season. Occasional plants of 

 T. pratense were observed; one tomato plant, a three-year old grape 

 vine and a young cherry tree. 



'Weed Notes. 



HoRSE-iSrETTLE (S. CaroHuense L.). — Mr. Polhemus, of Rocky Hill, 

 handed the Director a specimen of this weed for identification, stat- 

 ing that it was becoming troublesome in the meadows in his neighbor- 

 hood. 



Corn Cpiamomile {A. arvensis L.). — The manner in which this 

 plant can adapt itself to conditions may be seen in one portion of the 

 College campus. Instead of being destroyed by frequent clippings of 

 the la\Mi-mower, its usually erect or nearly erect stems have become 

 prostrate. Roots are put forth from their Joints, binding them closely 

 to the ground, and one plant will spread over a considerable area in a 

 single season. 



Ground Ivy {N. GlecJioma Benth.). — In some of the lawns about 

 New Brunswick this weed is becoming quite conspicuous. 



AiLAXTHUS (A. glanduJosus Desf.). — The owner of a lawTi contain- 

 ing a few ailanthus trees is annoyed during late summer and fall by 

 the great number of ailanthus seedlings. One of the trees was cut 

 down in the spring, and from its large "surface"' roots many sprouts 

 were sent up throughout the season.
