Iininediatel\- upon my arrival at hcidcpiarters, I proceeded 

 once more to the Upi)er Sacramento valley to collect such seeds 

 as I cotild not procure before. 



Havino^ packed up my collections, and sent part by water 

 to San Francisco, I left on the 30th of June for Monterey, in 

 company with an American whom I had eno^nj^ed as a <,niide. 

 Towards evening of the same day we arrived at the junction of 

 the Feather river with the Sacramento; and passinjjf, the follow- 

 ing morning, our luggage over in a canoe, we swam the horses 

 across, the distance from shore to shore being not less than 300 

 yards. We now continued our course over the prairie on the 

 right bank of the Sacramento river for two days, and crossed 

 again to the south side in a ferry boat at the Straits of Car- 

 quinez. 



A kind of tertian fever, accompanied by violent headache, 

 under which I had been suffering some days previous to my de- 

 parture, here developed itself into a quotidian fever and ague, 

 which for want of proper medicines, the constant exposure to a 

 tropical sun during the day, and camping out at night, soon re- 

 duced me to such a state of debility as scarceK- to be able to sit 

 on horseback. 



From the Straits of Carquinez we passed along the Bay of 

 San Francisco to the Pueblo of San Jose, and reached Monterey 

 on the 8th of July. 



Soon after m}' arrival (having, with the assistance of my 

 little medicine chest, cured myself), I continued my excursions 

 about Monterey as far as my returning strength permitted, and 

 collected such kinds of seeds as I thought worth preserving. 

 Towards the end of July I went over to Santa Cruz for a similar 

 purpose, and whilst visiting a family upon their farm, with 

 whom I had become intimately acquainted during their winter 

 residence in Monterey, I was again taken ill with fe\er and agr.e. 

 In addition to the seeds which I collected in the Santa Cruz 

 mountains last year, I found the evergreen chestnut with ripe 

 fruit. This shrub, of which I had been most anxious to procure 

 seeds, attains the height of ten feet and is of a pyranudal form.
