16. The place where the men live is always in the fore-part of the ship, but their berths should be changed in a certain rotation, because of the inequality of the condensation. It is not advisable to place the kitchen in the quarters of the crew in order to diminish the consumption of coals, because an accumulation of moisture is thereby increased. The officers and _savans_ occupy a common messroom in the after-part of the ship, and sleep in little cabins ranged round it. The power to withdraw occasionally from the presence of those who must be together for years is an important element of harmony. Sir John Ross and his officers in 1833, even in the miserable hut built on the Fury coast, did not occupy the common messroom heated by a stove, but preferred separate cabins, the temperature of which seldom rose above the freezing point, and in which they had to suffer much from the accumulation of ice. All the living rooms should be provided with waterproof carpets. Their heating by means of the common stoves is objectionable, because of the unequal distribution of warmth. An even temperature is best maintained by the use of the Meidinger “Fullofen,” which has the further advantage of consuming only a small quantity of coals. Hot-air flues are, perhaps, preferable even to these, because they better prevent the freezing of the moisture in the cabins, and indeed in every part of the ship. 17. An Arctic ship should be provided with an iron-plated washing and drying closet, without which the washing of linen would be restricted to the few weeks of summer weather. This closet may also be used as a bath-room, an important means of promoting health. The lighting of the living rooms by petroleum sufficiently answers all purposes; in the cabins, however, stearine candles are to be preferred either to it or any other oil. The construction of the lamps used in making observations in the open air during the long Arctic darkness is a matter of the greatest importance. Those used in the second German North-Pole Expedition were of peculiar excellence, and never failed in their difficult service. Massive lamps, with glass globes protected with wire, and burning petroleum in preference to common oil, should be used on deck, and as they are employed for so many purposes and exposed to so many risks, a plentiful supply of them should be provided. In the huts on the deck, built over the hatchways, train-oil may be used with advantage, if the lamps are so constructed that the flame may heat the reservoir containing the oil.
