SANTA EOSALIA AND SANTA AGUEDA PLANTS. 



From San Pedro and Raza Island Dr. Palmer visited two places on 

 tbe eastern side of the peninsula of Lower California, namely, Santa 

 Rosalia and Santa Agueda. At the first-named place he spent ten days 

 (February 20 to March 3), and after visiting Santa Agueda returned 

 for another day (March 15). This locality is 92 miles nearly northwest 

 from Guaymas. The country is hilly and rongli, covered with rocks. 

 Only two hea'tfy rains have fallen this season ; the strong northwest 

 winds which prevail here soon destroyed any indication of rain. Only 

 the most favorable circumstances admit of plants blooming at this 

 season, 



March 4-5 was spent at Santa Agueda, 10 miles from Santa Rosalia, 

 Dr. Palmer says this locality is watered by springs and surrounded by 

 low stony mountains, with a thin, diversified vegetation that now looks 

 parched ; even the cactus is without flowers. The small patches of land 

 that can be cultivated afford but few plants, and the great number of 

 domestic animals kept here (owing to the springs) devour everything 

 outside of the inclosures except what is so absolutely bitter or f horny 

 that they can not do so. All the vegetable used by the miners a,. Santa 

 Rosalia are brought from this place.
