A traveling sledge weighs about twenty-five pounds, but a freight sledge is much heavier.
A good team will travel from forty to sixty miles a day with favorable roads.

Sometimes a hundred a day may be accomplished, but very rarely.
Once an express traveled from Petropavlovsk to Bolcheretsk, a hundred and twenty-five miles, in twenty-three hours, without change of dogs.
Wolves have an inconvenient fondness for dog meat, and occasionally attack travelers.

A gentleman told me that a wolf once sprang from the bushes, seized and dragged away one of his dogs, and did not detain the team three minutes.

The dogs are cowardly in their dispositions, and will not fight unless they have large odds in their favor.

A pack of them will attack and kill a single strange dog, but would not disturb a number equaling their own.
Most of the Russian settlers buy their dogs from the natives who breed them.
