FLORA OF McXABS ISLAND, HALIFAX, N. S. BARHOUR. 567 



II, — It is through the leaves, flowers and stem that this influ- 

 ence acts, more than by the roots, for often when applied 

 to the latter, the results take longer to arrive at. Some- 

 times it even appears to act as a stimulant when applied 

 directly to the roots. 



III. — Colour is always aifected practically, and ])urple flowers 

 and leaves seem to be more influenced than a good many- 

 lighter ones. 



TV. — In ma'ny instances, the results obtained are more or less 

 the opposite to those seen when natural influences, such as 

 wind, rain, heat or cold are applied. Thej are also the 

 reverse of natural sleep. 



v.— Some flowers transpire under the influence of a narcotic, 

 and those which do most are the hardest to be affected. 



VI. — Though I have 'not mentioned it in my experiments, 

 flowers slightly under the influence of a narcotic may 

 recover if removed from it ; those deeply under it rarely, if 

 ever, do. 



VII. — Cell contents become altered. Granules may l>ecome dis- 

 organized or swell. 



The practical reasons for my experiments are the same as so 

 many others have done them for, and resolve themselves into 

 three questions — "What are the best flowers and plants for a 

 town or house in and around which noxious chemical products 

 are formed ? Which are those least likely to be affected by soot, 

 dust, harmful vapours, etc., containing narcotising elements? 

 How^ may we still keep our towns and parks beautiful under 

 such conditions ? These simple experiments with wild flowers 

 throw little light, I gi-ant, on such things, but possibly one or 

 two ideas may be gained, although similar experiments accurate- 

 ly^ conducted have often been done, which may be the stepping 

 stones to greater efforts on the part of those who are interested 

 in the beautifying of their native city, and who can teach those
