We pause for a moment amid the silent tranquillity to sum up our experience while gliding along this beautiful and peaceful inland sea on the return voyage. The author does not hesitate to pronounce Alaska to be one of the most attractive regions in the world for summer tourists. From early June to September the temperature prevailing upon the entire route is equable, the thermometer ranging all the while between sixty and seventy degrees Fah. The progress of the steamer always creates a gentle and agreeable breeze, which renders warm clothing desirable, especially at early morning and in the evening, though these are periods not so distinctly defined as with us in New England. An overcoat is rarely rendered necessary or desirable. If the mosquitoes are troublesome at certain places on shore, in marshy regions, they are never so on the water, as the breeze inevitably drives such insects away. Let us say especially there is no other such inviting resort for pleasure yachts as this inland, island-dotted sea of Alaska. If the fogs put in an appearance sometimes in the morning, they are after a while burned away by the warmth of the sun. Local rains on shore are to be occasionally endured, but they are no great drawback to observation and brief excursions. At Sitka, Wrangel, and Juneau several showers may occur during the day, with intervals of bright and cloudless skies between. We have witnessed seven copious, well-sustained showers of rain on a May forenoon in Chicago, the intervals sandwiched with sunshine of gorgeous clearness and warmth. Why pretend that Alaska is exceptional in this respect? The weather is not perfect, according to our estimate, anywhere. Finally the extended trip upon the boat was found to cover a little over two thousand miles in all, and was with us one of continuous pleasure, enlivened by as bright and cheerful weather as one experiences on an average elsewhere, winding among an immense archipelago of mountains, emerald islands, and land-locked bays, through narrow channels dominated by precipitous cliffs, and crossing broad, lake-like expanses as placid as the serene blue overhanging all. No other government on the globe, in this nineteenth century, would permit so large and important a portion of its territory to remain unexplored. Congress should send at once a thoroughly equipped scientific expedition, competent to report minutely upon the geology, fauna, flora, and geography of this immense division of the country. It is more than an oversight, it is a gross blunder, not to do this without further delay. If our own pen-pictures of this neglected Territory shall incite to the fulfillment of such an act of official duty, these pages will have served at least one important purpose.
