The first white woman that ever visited the Yosemite was a Madame Gautier, the housekeeper at the Franklin House, Mariposa. A few days afterwards Mrs. Johnny Neil, of Mariposa, and Mrs. Thompson, of Sherlocks, came up. Their courage and endurance should certainly be made a matter of record. The next ladies to visit the place were of the party with Mr. Denman, of “Denman’s High School,” in San Francisco. After this it ceased to be a novelty to see ladies in the Yosemite. Mr. Denman published an account of his trip. His communication was a well written and instructive article. It was the _first_ description that gave the public any definite idea of the magnitude of the scenery, or any accuracy of measurements of the heights of the cliffs and water-falls. I was present when Mr. Peterson gave to Mr. Denman the results of his observations, and consequent estimate of heights. I was amused at Mr. Denman’s expressions of surprise, and his anxious but polite inquiries of Mr. Peterson if he was _sure_ his angles had been correctly marked. Peterson colored slightly at the doubt implied of his professional skill, but with unusual politeness and apparent cheerfulness offered to make a resurvey of El Capitan or any other prominent cliff that Mr. Denman would select for measurement. The offer was quickly accepted, and a new determination of several points of interest were made. From the notes taken, each of the gentlemen computed the heights. Mr. Peterson soon figured up the result of his work, and patiently awaited the result of Mr. Denman’s, before he announced his own. After figuring for sometime, Mr. Denman expressed a belief that he had made a grand mistake somewhere in his calculations, for he had made the result more than the previous estimates and above all seeming probabilities. They then compared figures and found but little difference in their heights. Mr. Denman again worked up the notes, and was convinced of their correctness and reported his conclusions in his descriptions. The first house erected in the valley for the accommodation of visitors was _commenced_ in 1856, by Mr. Walworth and Mr. Hite. It, was made of “boards” rived out of pine logs. The site was that of our old camp-ground of 1851, or a little above it, and nearly opposite the Yosemite Fall.
