The province of the Society thus being one of instruction its suc- 

 cess will depend upon the amount of accurate and pertinent informa- 

 tion, which it can accumulate for distribution to the public. It is 

 urged therefore that persons who are in a position to witness needless 

 depredations upon our native plants will kindly communicate the 

 details of such cases to the secretary 1 of the Society. The executive 

 board of the Society is especially desirous of securing accurate data 

 regarding the sources of supply to venders of wild flowers on streets 

 and at railway stations, also the present sources of the mountain 

 laurel, holly, and other Christmas greens, which are brought to our 

 cities in astonishing quantities during the winter season. Informa- 

 tion will always be welcomed regarding plants to be especially pro- 

 tected, nature of leaflets which should be issued, places where notices 

 should be posted, and names of persons desiring membership in the 

 Society or willing to sustain or participate in its work.
