About the time of our arrival in the bay, when the thermometer had fallen nearly to _zero_, the condensation of vapour upon the beams of the lower deck, and in the cabins near the hatchways, commenced just as it had done at a similar temperature before. To remedy this evil, no time was lost in lighting a fire in the warming-stove upon the orlop-deck, everything being previously moved from its neighbourhood that was likely to create danger. The iron tanks in the main hatchway were laid bare on the top, and the interstices between them filled with sand, to form a secure platform in front of the fire; and the sailroom, bulkheads, and stancheons covered with sheet copper. Four steady men, of whom one was a petty officer, were appointed to attend the fire in regular watches, being made responsible for the due expenditure of the fuel, and for the safety of everything about the stove. They had likewise particular charge of the fire-engine, buckets, and two tanks of water, all of which were kept in the hatchway in constant readiness in case of accidents. In addition to these precautions, some general regulations were established for stationing the officers and men in the event of fire; and a hole was directed to be kept open in the ice alongside each ship, to ensure at all times a sufficient supply of water. In twelve hours after lighting the stove not a drop of moisture remained. The regulations for the maintenance of due cleanliness among the ships' companies were principally the same as those established on the preceding voyage. As a source of rational amusement to the men, soon after our arrival I proposed to Captain Lyon and the officers of both ships once more to set on foot a series of theatrical entertainments, from which so much benefit in this way had, on a former occasion, been derived. This proposal was immediately and unanimously acquiesced in; Captain Lyon obligingly undertook to be our, manager, and, some preparation having been made for this purpose previous to leaving England, everything was soon arranged for performing a play on board the Fury once a fortnight. To furnish rational and useful occupation to the men on the other evenings, a school was also established for the instruction of such of the men as were willing to take advantage of this opportunity of learning to read and write, or of improving in those acquirements. While these internal arrangements were making, the interests of science were not neglected. A day or two after our arrival, Mr. Fisher and myself selected a spot for the portable observatory, which was immediately erected for the purpose of making magnetic observations; and, as soon as the carpenters could be spared from the necessary duties of the ships, a house was built for the reception of the instruments requisite in conducting the other observations and experiments.
