In the Arctic Regions, on the other hand, with the perfect and light equipment that is carried nowadays and with the modern and accurate long-range firearms, so different from those used by Franklin, Rae, Richardson, Back, and others, who actually starved with reindeer in sight, there is little chance of explorers not being able to obtain food supplies. It is true there may be difficulty on occasions in obtaining food by one's own gun, in certain districts, for several days, but it is scarcely possible now to be reduced to such extremities as Arctic explorers were in the days of Franklin and Rae, with their heavy equipment and primitive firearms.
