As facts observed have a value far above theories, I 
shall give the substance of numerous observations made 
by me, at Greenfield, Massachusetts, in the Whiter of 
1850-7, on vi'intering bees in the open air ; 
Jan. 9th, 1857.—Examined a number of stocks with 
Winter-passages in their combs, and with all the holes in 
their honey-board uncovered. Tlie previous month had 
been extremely cold, and, for three days before the exami¬ 
nation, the thermometer had been one-half of the time 
below zero, and only once ten above, the wmd blowing an 
almost continuous gale. In none of these hives could I find 
any frost or dampness, or any bees killed by being caught 
away from the main body of the colony. In a tempera¬ 
ture below zero, they would rush up from their combs on 
the slightest jar of their hives, rapidly pouring through 
the Winter-passages, and showing their ability to reach 
any of their stores.* In a few colonies, to which no up¬ 
ward ventilation had been given, the interior walls of the 
hive, and many of the combs were coated tvith frost. 
Jan. 14tu. —Carefully e.xainined three hives. No. 1, 
made of boards seven-eighths of an inch thick, had stood 
with its honey-board removed, the same as would show 
by removing (/) in Plate III., Fig. 9. It had a good stock 
of bees, and, although the mercury in the morning was 
10-^-° below zero, there was scarcely any frost in the hive. 
The bees were dry and lively, and the central combs con¬ 
tained eggs and unsealed brood. No. 2 contained an 
equally strong stock, in a thin hive holding eighteen 
frames, ten of which (five on each side) had no combs. 
This hive had no upward ventilation, and was very frosty. 
• On n cold November day, I have found bees, in a hive without any Winter* 
lnuvsuges, separated from the main cluster, and so chilled as not to be able to move; 
wlilU', with tho thoiTuomcter many degrees below zero, 1 have repeatedly noticed, 
in other hives, at one of the holes iimdo in the comb, a cluster, varying in site, 
ready to rush out at the slightest jar of their hive.
