gJ Aside from frost warnings on a number of days for
hbe lowlands of New Jersey and for the more northern spd elevated districts of the Altsntic States and the Qhio Valley, the important warnine issued durin the bonth were in connection with two storms o f the w.estern Atlantic. The first of these originated in low latitudes east of the Lesser Antilles, the French S. S. && Rose encountering it about 200 miles east of Mar- &ique. This vessel received slight damage. Moving mst-northwestward this disturbance passed the vicinity dSsC. Martin on the 16th on a northwest course and later m m e d and passed over Bermuda during the early SrlQrniug of the 21st. At Hamilton, Bermuda, the lowest h m e t e r reading reported was 28.72 inches, the wind -chmg hurricane velocity. Preliminary advices con- oeming this disturbance were issued on the 14th and bEey were continued dad until after the disturbance

While the fnst of these disturbances wm in regress another developed off the east Florida coast, &e jirst evidences of it appearing the mo of the 18th, when *northeast warnine were 3 l a y e z o n g the coast from Cape Henry, Va., southw to Bmwick, Ga. Later during the same day northwest storm-warnings were displa ed at and between Jacksonville and Jupiter Inlet Fla. h i s disturbance increased in intensity and moved slowly northwestward during the 18th. On the morning of the 19th its center was near latitude 30' N. and low- tude 78" W., and moving more to the northward, but were repeated on the 19th and vesaele off the South At antic coest were again advised to ex- cise caution. Prom its position on the 19th this dis turbance advanced north and then northeastward and passed off Cape Hatteras in an eastarly direction on the
22d. On the early afternoon of the 20th stom-warnigs were ordered displayed on the .coast northward from the Virginia coast to Delaware Breakwater and the morning of the 21st the dis lay was extended northward on the coast to Boston, &ass. No observations have

9 in the been received of the lowest barometer re immediate center of this disturbance, but the act that winds of hurricane velocity occurred off the North Carolina coest would lead to the supposition that the dis- turbance was one of major intensity, but not actually of tropical origin. So far as known no American vessels were destroyed in either of these disturbances. It is a fact of importance, however, that the Diamond Shoals Lightship was blown 12 miles from its moored position
, by the second of these disturbances. Details concerning these two disturbances will be found elsewhere in this number of the R~v~~w.--Edward a. Bowie.
