“14th. Last night, above 12 P.M., commenced raining; 3 A.M., rained steadily; 7 A.M., same weather; 8.20 A.M., a line of low storm-cloud, or scud, showing very sharp and white on the dark back-ground all along the southern sky. This line continues until noon, about 10° at the highest, showing the northern boundary of the storm to the southward; 8 P.M., same bank visible, although in rapid motion eastward; same time clear overhead, with cirrus fringe pointing north from the bank; much lightning in south (W. fresh); so ends.
“15th. Last night a black squall from N. W. passed south without rain; at 3 A.M., clear above but, very black in south (calm below all the time); 9 A.M., the bank in south again throwing off rays of cirri in a well-defined arch, whose vortex is south; these pass east, but continue to form and preserve their linear direction to the north; no lightning in south to-night.
“16th. Clear all day, without a stain, and calm.
“17th. Fine and clear (N. E. light); 6 P.M., calm.
“18th. Fair and cloudy (N. E. light); 6 P.M., calm.
“19th. Fine and clear (N. fresh); I. V. visible in S. W.
“20th. 8 A.M., bank in N. W., with beautiful cirrus radiations; 10 A.M., getting thick, with dense plates of cream-colored cirrus visible through the breaks; gloomy looking all day (N. E. light).”
The letters in a parenthesis signify the direction of the wind.
During this month there were three distinctly marked periods of belts of showers, preceded by “fresh” or “strong” south wind, and followed by the N. W. There was a period when a belt of less intense stratus, without much wind, occurred (28th, 29th, and 30th of June). This was followed by a distinct belt of showers and fresh S. wind, on the 2d of July, and by the N. W. wind and clear weather, on the 3d.
During the rest of July it was more irregular, with the exception of the 7th, 8th, and 9th, when another belt and revolution occurred.
