"Most assuredly," answered the topographer. "There are thousands upon thousands of acres of land here, which would return immense crops, and all along up the river. All that is needed is a market for the produce."

"But how about moving it?" asked the boy.

"The Sushitna River is navigable for a hundred miles to steamers of light draught, and to barges. You'll see this all in farm like the Red River Valley some of these days."

The thermometer staying about ten degrees below zero made the thought of waving crops a strange one, but this very low temperature was the best of all possible advantages to the party, as it was good for dog traveling. Cold enough to keep the trails in excellent shape, it was not too cold for traveling in comfort. Two days sufficed to bring the party to the point of land jutting out in the sea that makes Cook Inlet a double bay, but at this point, which is known as North Foreland, a sudden drop in temperature, coupled with a gale of wind, delayed progress, so that in all six days had elapsed from the time of landing until they pulled into Tyonok. This is one of the oldest mainland settlements of southwestern Alaska, having been used as the mainland port of the former Russian capital, Kodiak, on Kodiak Island.

A General View of Tyonok.

The most northerly harbor in Cook Inlet, usually reached by seagoing vessels. Prospectors' tents along the beach.

One day was spent at Tyonok purchasing and packing larger supplies of dog feed, of which only enough for a couple of weeks' journey had been taken from Seldovia. Dog-feed is the one article that can always be procured from the natives, but as there was no assurance that the Survey party would meet any natives up the river at that time of year, Rivers decided to complete his supply before he started. Despite the importance of Tyonok as a trading post, almost ranking as a prominent seaport, Roger found it to consist of about forty-five rude log shanties, only one, the general store, being more than one story in height. In summer, so the lad was informed, hundreds of tents are erected along the shore, but the winter population, for such an important point, is ridiculously small.
