Martinez Jan. 13, 1890 Dear Mr Johnson, That is a pretty big block of mountains you have indicated for our article.
I fear the description will seem lean scrawny, however I will gladly do the best I can with it hoping to call attention to
its value as our grand Central Park in the Sierra. There will be no lack of sketches or photographs for illustrations. Keith
has some Tuolumne Canon sketches some of mine can be fixed up perhaps, photographs of the Big Meadows the adjacent can be
had, but of the interesting region about the head of the north fork of the San Joaquin only my poor pencil sketches are available
as far as I know.
