Mr. and Mrs. J. C. Lemmon are off among the Santa Catarina mountains of Arizona. In a recent letter to the Pacific Rural Press Mr. Lemmon says: " We packed ourselves (wife and I) with blankets, provisions, botanical paper, etc., at once and started for the distant mountains, toiling along amidst the hot sand or over the numerous hills, beset with thorny mesquite bushes or with the ten-times-more-to-be-dreaded cacti, with keen, barbed, stinging needles. 0! how we have been punished whenever too hasty or heedless.

We have established a temporary camp in a cave near a little spring at the very base of the highest peak of the mountains, and often visit it two or three nights in succession. From this secure retreat from prowling natives we sally out early in the morning packed with botanical portfolios, food and water for the day, and at once proceed to climb the rugged steeps, contending all the way against the thorns of the mesquite, the bayonets of yucca and the fiendish needles of cacti, each of these terrible defensive plants being found clinging to the very pinnacles of these mountains, as if guarding vast treasures.

After a long day of weary, painful climbing, we retreat to the cave and pass the night. Next day we must rest and dry out our plants gathered. The second day we climb again, and so the rare or new plants of the mountains of the Santa Catarina are being gathered. Thus are your late Oakland citizens rusticating and enjoying themselves, while adding now and then a new plant or a valuable fact to the common stock of knowledge.
