. N. E. storms, whether they set in from that quarter in the commencement, or veer to it afterward, when they do "change" round, more frequently veer by the S. to the S. W. in clearing off, than back through the N. into the N. W. The former, in accordance with his theory, they can not do, as the reader can see by passing the left side of the card over his place of residence on the map from S. W. to N. E. 3d. N. E. storms often pass off without hauling by S. or backing by N., and with or without a clearing off shower, the _wind shifting and coming out suddenly at S. W._ This they could not do in accordance with his theory, as slipping the card will show. 4th. From June to February it is _exceedingly uncommon_ for a N. E. storm to back into the N. W. They do so more frequently from February to May, especially about the time of the vernal equinox and after; and then, because the focus of precipitation and storm intensity of the extra tropical zone of rains is S. of 42 deg. east of the Alleghanies. His theory requires them to back by N. into N. W. _in all cases, when they set in N. E._ 5th. When they do back from the N. E. into the N. W., it rarely indeed continues to storm after the wind leaves the point of N. E. by N., and generally, if it does continue stormy, _the wind is light_, and not a gale, how violent soever the gale from the eastward may have been. Usually, by the time the wind gets N. W., it has cleared off. This, Mr. Redfield, as we shall see, evades by embracing the N. W. fair wind as a part of the same gale. According to my observation, therefore, a _very large proportion_ of the _N. E. storms_, and they are a majority of the most violent ones of our climate east of the Alleghanies, do not _commence, continue_, or _veer_ in accordance with his theory, but the _reverse_; and so long as this is so, I can not receive his theory as true. 6th. S. E. storms do not always, or indeed often, conform to the requirements of his card. When they set in violently at S. E., and continue so for hours without veering, the axis of the storm should be over us, and the wind should change _suddenly_ to N. W. This did not occur in the storm of Sept. 3, 1821, nor does it often, if ever, occur in the summer or early gales of the autumnal months. In the later storms of autumn, and as often in those which are very gentle as any, and in the winter months when S. E. gales are rare, it does sometimes so change after the storm clo
