Assigned to the Division of the Pacific
We ascended Owens River valley to the source of that stream, recrossed the mountains by the “bloody” cañon, and descended through the great Yosemite valley, which from the higher altitude looked like a little “hole in the ground.” That was the least interesting of all my four visits to that wonderful work of nature. Our round trip occupied about seven weeks.
At our last camp, in Tuolumne meadows, some time in August, after the temperature had been above eighty degrees in the daytime, it fell below thirty at night. I contracted a cold which developed into pneumonia, from which I did not recover for many months. It was during my convalescence that I went with Colonel B. S. Alexander to the Hawaiian Islands, under an arrangement previously made with the War Department.
It was the year 1872 when I and Colonel Alexander, the senior engineer officer on the Pacific coast, who had applied to the War Department and obtained an order to visit the Hawaiian Islands for the purpose of reporting to the War Department, confidentially, the value of those islands to the United States for military and naval purposes, went to Hawaii with Rear-Admiral Pennock on the flag-ship California, and returned, three months later, on the war-steamer Benicia. During our stay we visited the largest island of the group,—Hawaii,—and its principal seaport,—Hilo,— and the great crater of Kilauea. We made a careful examination of the famous harbor of Pearl River, in the island of Oahu, a few miles from Honolulu, including a survey of the entrance to that harbor and an estimate of the cost of cutting a deep ship-channel through the coral reef at the extremity of that entrance toward the sea.
At that time the young king Lunalilo had just ascended the throne made vacant by the death of the last of the ancient reigning house of Hawaii. The policy of the preceding king had been annexation to the United States; but the new sovereign and his advisers were opposed to that policy, although very friendly to Americans, and largely controlled by their influence in governmental affairs. It was manifest that the question of annexation ought not to be discussed at that time, but that action ought to be taken at once to secure to the United States the exclusive right to the use of Pearl River harbor for naval purposes, and to prepare the way to make annexation to the United States sure in due time. This could readily be done by making such concessions in favor of the products of Hawaiian industries as would develop the resources of the islands and increase their wealth, all of which would be to the ultimate benefit of the United States when the islands should become a part of this country.
