uplands. There was also frost here on the 28th and 30th, and the observer says 

 a frost in An^cust was never before known in that part of the country. 



Illinois. — The registers are from nine stations, each in a difftM-ent county, and 

 extending from the northern border of the State to the latitude of the mouth of 

 the Missouri river. On the morning of the 23d the temperature at nearly all 

 the stations Avas low, but it increased during the day, and a't 9 p. m. at all the 

 stations, with only two exceptions, (and these barely so.) the temperature was 

 higher than at the same hour on any day of the month. On rhe 24th the cold, 

 which continued to the end of the month, set in. At 7 i. m. it was from 7 to 

 21 degrees lower than on the 23d, at 2 p. m. 16 to 34 deg;- es lower, and at 9 p. m. 

 26 to 32 degrees. In Hancock and Knox counties a light frost was recorded 

 on the 25th. On the 29th frost wis noticed at a number of places, but on the 

 30th it was more general and severe throughout the State. At Gale.-<!jurg, 

 Knox county, water froze. 



Indiana. — -The registers are from five counties, situated at both extremities, and 

 in the interior of the State. The depression seems to have begun on the 24th, 

 after the 7 a. m. observation. It was warmer at all the five sfations at that 

 hour on the 24th than on the 23d, but dm-ing the forenoon the temperature fell; 

 the 2 p. m. observation at Rockville, Park county, being 17 degrees lower than 

 at 7 a. m. ; at South Bend, St. Joseph's county, and at New Harmony, Posey 

 countv, 10 degrees lower; and at the other two stations only 1 and 4 degrees 

 higher. At all the stations it was much colder in the afternoon and night of the 

 24th than on the 23d — at 2 p. m. from 10 to 29 degrees lower, and at 9 p. m. 

 from 14 to 30 degrees lower. A light frost is recorded in St. Joseph's county 

 on the 26th, and in Park county on tlie 26th and 27th. The frost was general 

 on the 30th and 31st. At New Albany one could readily write in the fi-ost on 

 boards and fences ; and at New Castle ice was formed an eighth of an inch 

 thick in shallow water. 



Michigan. — Two registers have been received — one from Ypsilanti, and one 

 from Monroe, both in the southeast corner of the State. At Tpsilanti no ob- 

 servation is recorded at 9 p. m. on the 23d, biit at 7 a. m. and 2 p. m. of that day 

 the temperalure was lower than at, those hours on any previous day of the 

 month. It rose again during the night or next morning, and on the 24th at 7 

 a.m. it was 76, being 20 degrees higher than at that hour on the preceding day, 

 and higher than on any day of the month at 7 a. m., except the 1st, 2d, and 

 18th, on each of which days it was 78. During the forenoon of the 24th the 

 temperature fell rapidly, and at 2 p. m. it was 8 degrees, and at 9 p. m. 22 degrees 

 lower than at 7 in the morning. At Monroe the cold also began early on the 

 23d, and the mean temperature of the day was lower than on any previous day 

 of the month, except the 17th, but the morning observation of the 24th does not 

 exhibit the same comparative elevation of temperature as at Ypsilanti. The 

 cold continued through the remainder of the mouth, and produced a killing frost 

 on the 29th and 30th. 



OJiio.^-T\ie registers are from twelve counties, and represent nearly all parts 

 of the State, from Lake Erie to the Ohio river. Without presenting the details 

 of all these, it may be stated generally that the temperature was high on the 

 morning of the 24th, and the depression which marked the end of the month 

 began at some stations in the forenoon, at some in the night of that day, and at a few 

 not until the morning of the 25th. The only frosts reported before the 30th 

 were at Newark, on the 26th. and at Urbana, on the 27th ; of the latter the ob- 

 server remarks that it did not injure his most tender exotics. On the 30th and 

 31.-.' frosts prevailed throughout the State, at some places damaging corn, at 

 others injuring only tender vines. The observer at Newark states that there 

 were six frosts in June, two in July, and three in August. 



Pennsylvania. — Only three registers have been received from this State — one 

 from Canousburg, near the southwest corner, one from Fleming, in the centre.
