An important consideration, is the variety of food obtainable in the arctic regions.  We need not particularly classify the creatures found in the two seasons of summer and winter, but may enumerate the principal together.  Of animals fit for food are musk-oxen, bears, reindeer, hares, foxes, &c.  Of fish, there is considerable variety, salmon and trout being the chief and never-failing supply.  Of birds, there are ducks, geese, cranes, ptarmigan, grouse, plovers, partridges, sand-larks, shear-waters, gannets, gulls, mollemokes, dovekies, and a score of other species.  We personally know that the flesh of bears, reindeer, and some of the other animals, is most excellent:  we have partaken of them with hearty relish.  As to foxes, Ross informs us that, although his men did not like them at first, they eventually preferred fox-flesh to any other meat!  And as to such birds as gannets and shear-waters, which are generally condemned as unpalatable, on account of their fishy taste, we would observe that the rancid flavour exists only in the fat.  Separate it, and, as we ourselves can testify, the flesh of these birds is little inferior to that of the domestic pigeon, when either boiled or roasted.  The majority of the creatures named may be captured in considerable numbers, in their several seasons, with only ordinary skill.  But necessity sharpens the faculties of men to an inconceivable degree; and when the life of a crew depends on their success in the chase, they will speedily become expert hunters.  It is true that the wild animals habitually existing in a small tract of country may soon be thinned, if not altogether exterminated; but bears, foxes, &c. continue to visit it with little average diminution in numbers.  The fish never fail.  The quantity of salmon is said to be immense, and they can be preserved in stock a very long period by being simply buried in snow-pits.  The birds also regularly make their periodical appearance.  Besides, parties of hunters would be despatched to scour the country at considerable distances, and their skill and success would improve with each coming season.  In regard to fuel, the Esquimaux plan of burning the oil and blubber of seals, the fat of bears, &c. would be quite effective.  In the brief but fervid summer season, every inch of ground is covered with intensely green verdure, and even with flowers; and there is a great variety of wild plants, including abundance of Angelica, sorrel, and scurvy-grass, also lichens and mosses, all of antiscorbutic qualities.  We have ourselves seen the Laplanders eat great quantities of the sorrel-grass; and the Nordlanders told us that they boiled it in lieu of greens at table.  These vegetables might be gathered each summer, and preserved for winter use.
