On the receipt of this intelligence, I immediately drew up a paper, which was signed by myself, Messrs Reed, Jacob, Lippincott, and Grayson, offering our services as volunteers, and our exertions to raise a force of emigrants and Indians which would be a sufficient reinforcement to Colonel Fremont. This paper was addressed to Mr. Kern, the commandant of Fort Sacramento, and required his sanction. The next morning (29th) he accepted of our proposal, and the labour of raising the volunteers and of procuring the necessary clothing and supplies for them and the Indians was apportioned. It commenced raining on the night of the twenty-eighth, and the rain fell heavily and steadily until twelve o'clock, P.M., on the twenty-ninth. This is the first fall of rain since March last. About one o'clock, P.M., the clouds cleared away and the weather and temperature were delightful. About twelve o'clock, on the 30th, accompanied by Mr. Grayson, I left New Helvetia. We crossed the Sacramento at the _embarcadero_, swimming our horses, and passing ourselves over in a small canoe. The method of swimming horses over so broad a stream as the Sacramento is as follows. A light canoe or "dug-out" is manned by three persons, one at the bow one at the stern and one in the centre; those at the bow and stern have paddles, and propel and steer the craft. The man in the centre holds the horses one on each side, keeping their heads out of water. When the horses are first forced into the deep water, they struggle prodigiously, and sometimes upset the canoe; but, when the canoe gets fairly under way, they cease their resistance, but snort loudly at every breath to clear their mouths and nostrils of the water. Proceeding ten miles over a level plain, we overtook a company of emigrants bound for Nappa valley, and encamped with them for the night on Puta creek, a tributary of the Sacramento. Five of the seven or eight men belonging to the company enrolled their names as volunteers. The grass on the western side of the Sacramento is very rank and of an excellent quality. It commenced raining about two o'clock on the morning of the 31st, and continued to rain and mist all day. We crossed from Puta to Cache creek, reaching the residence of Mr. Gordon (25 miles) about three o'clock P.M. Here we enrolled several additional emigrants in our list of volunteers, and then travelled fifteen miles up the creek to a small log-house, occupied temporarily by some of the younger members of the family of Mr. Gordon, who emigrated from Jackson county, Mo., this year, and by Mrs. Grayson. Here we remained during the night, glad to find a shelter and a fire, for we were drenched to our skins.
