aze in S., with

prismatic shades, chiefly greenish-yellow; 7 A.M., (S.-S.-E.
freshening,) thick in W; 8 A.M., (S. fresh) much cirrus, thick and
gloomy; 9 A.M., a clap of thunder, and clouds hurrying to N.; a reddish
haze all around; at noon the margin of a line of yellowish-red cumuli
just visible above a gloomy-looking bank of haze in N.-N.-W., (S. very
fresh;) warm, 86d; more cumuli in N.-W.--the whole line of cumuli N. are
separated from the clouds south by a clear space. These clouds are borne
rapidly past the zenith, but never get into the clear space--they seem
to melt or to be turned off N.-E. The cumuli in N. and N.-W., slowly
spreading E. and S.; 3 P.M., the bank hidden by small cumuli; 4 P.M.,
very thick in north, magnificent cumuli visible sometimes through the

the bank north.[17]

_July_ 4th. 6 A.M., a line of small cumulo-stratus, extending east and
west, with a clear horizon north and south 10d high. This band[18] seems
to have been thrown off by the central yesterday, as it moves slowly
south, preserving its parallelism, although the clouds composing it move
eastward. Fine and cool all day--(N.-W. mod.)--Lightning in N.

dark and incessant lightning in N.

but leaving a line of lighter sky south; much lightning all night, but
