October 15.—­I do not like to trouble the reader with a frequent reference to the myriads of fleas and other vermin which infest the rancherias and old mission establishments in California; but, if any sinning soul ever suffered the punishments of purgatory before leaving its tenement of clay, those torments were endured by myself last night.  When I rose from my blankets this morning, after a sleepless night, I do not think there was an inch square of my body that did not exhibit the inflammation consequent upon a puncture by a flea, or some other equally rabid and poisonous insect.  Small-pox, erysipelas, measles, and scarlet-fever combined, could not have imparted to my skin a more inflamed and sanguineous appearance.  The multitudes of these insects, however, have been generated by Indian filthiness.  They do not disturb the inmates of those casas where cleanliness prevails.

Having letters of introduction to General Vallejo and Mr. Leese, I delivered them this morning.  General Vallejo is a native Californian, and a gentleman of intelligence and taste far superior to most of his countrymen.  The interior of his house presented a different appearance from any house occupied by native Californians which I have entered since I have been in the country.  Every apartment, even the main entrance-hall and corridors, were scrupulously clean, and presented an air of comfort which I have not elsewhere seen in California.  The parlour was furnished with handsome chairs, sofas, mirrors, and tables, of mahogany framework, and a fine piano, the first I have seen in the country.  Several paintings and some superior engravings ornamented the walls.  Senora Vallejo is a lady of charming personal appearance, and possesses in the highest degree that natural grace, ease, and warmth of manner which render Spanish ladies so attractive and fascinating to the stranger.  The children, some five or six in number, were all beautiful and interesting.  General V. is, I believe, strongly desirous that the United States shall retain and annex California.  He is thoroughly disgusted with Mexican sway, which is fast sending his country backwards, instead of forwards, in the scale of civilization, and for years he has been desirous of the change which has now taken place.

In the afternoon we visited the house of Mr. Leese, which is also furnished in American style.  Mr. L. is the proprietor of a vineyard in the vicinity of the town, and we were regaled upon grapes as luscious, I dare say, as the forbidden fruit that provoked the first transgression.  Nothing of the fruit kind can exceed the delicious richness and flavour, of the California grape.

This evening Thomas O. Larkin, Esq., late United States Consul for California, arrived here, having left San Francisco on the same morning that we did, travelling by land.  Mr. L. resides in Monterey, but I had the pleasure of an introduction to him at San Francisco several days previously to my leaving that place.  Mr. L. is a native of Boston, and has been a resident in California for about fifteen years, during which time he has amassed a large fortune, and from the changes now taking place he is rapidly increasing it.  He will probably be the first American millionnaire of California.
