It would be of great interest to compare the aggregate prevalence of southwesterly winds and their velocity for a summer on the Isthmus with the corresponding facts for other parts of the province, but the data are not available, for there is no station for wind measurement in this district. I have not studied the subject minutely but the effects are plainly of two and perhaps of three kinds. First, there is the mechanical bending of the growing shoots giving them all a set in the northeast direction. Se


. Bulletin of the Natural History Society of New Brunswick. a b converging at the Isthmus. It would be of great interest to compare the aggregate prevalence of southwesterly winds and their velocity for a summer on the Isthmus with the corresponding facts for other parts of the province, but the data are not available, for there is no station for wind measurement in this district. I have not studied the subject minutely but the effects are plainly of two and perhaps of three kinds. First, there is the mechanical bending of the growing shoots giving them all a set in the northeast direction. Second, there is diminished branch growth on the windward side ; this is no doubt due to the greater transpiration upon that side, for it is known that increased transpiration is accompanied by lessened growth of the transpiring parts. With this is correlated, too, an observable greater abundance of dead branches on the windward side. Third, it is possible, though not probable, that branch-development responds, to some extent, irritably to wind direction as a stimulus, in which event we would have a phase of Rheotropism. One naturally looks in such a case as this for wind effects on other objects, but the only ones I have seen are occasional inclined telegraph poles, which on the Eddy road almost all lean strongly to the northeast, and the blowdowns in the burnt woods along the Ship Railway which a,re almost invariably in the same direction. More minute observa- tion may show effects on the small lakes of the marshes and even also in some of the details of tidal Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Natural History Society of New Brunswick.
