The want of facilities for transportation must be severely felt in the interior settlements of California. Steam vessels of the swiftest and most commodious character are the means of easy communication and transportation between San Francisco and the towns on Suisan Bay and the Sacramento, as far as Sacramento City. Communication by the same means will doubtless, soon be established between the different ports on the coast. But railroads and canals are requisites for increasing the social communication and drawing the people of all parts of the State more closely together. These, however, will not be long in demand, after the State has been admitted into the Union. The companies for such purposes will feel secure in their charter, and receive assistance from the government. There is nothing more efficacious in binding a people together and maintaining peace and harmony of action, than the mechanical facility of communication. The Atlantic States of the Union afford plentiful illustration and evidence of this assertion. Mark the differences of habit and sentiment in those States, where the means of intercourse between the inhabitants are comparatively few and far between. The interests of the different sections of a large State are of course, dissimilar, and produce the widest separation of feeling and opinion, which cannot be harmonized without the facilities of intercourse afforded by railroads and canals. In no State are there greater means of communication between the people of the different sections, than in Massachusetts; and in no State is there a more harmonious action in the Legislative department of the government. Let the railroads and canals be so constructed in California as soon as possible, and the effect will be the same. We have elsewhere mentioned and characterized the different harbors of California. There has been one other surveyed and pronounced excellent, and the beginning of a town made upon its shores. This is called Humboldt, after the distinguished traveller. It is about one hundred and seventy-five miles north of San Francisco. The river formerly called Pigeon, but now Trinity, empties into it. The harbor is sheltered from the south-west winds, but is exposed to the north-west. The north-west winds prevail from November till March, and are severe; but the south-west winds during the remainder of the year, are violent, and the harbor that is sheltered from them is considered a good one.
