If Congress has not provided by law for the government of this Territory, or its admission as a State, I would be very glad that the government would officially promulgate its views as to the civil authority now exercised here. Some important questions of law, involving both life and property, are now depending; and judges and jurors, without experience in these difficult questions, are called upon to act under great responsibility.

It appears to be the opinion of merchants in many of the ports of the Pacific—and they allege in support of it the advice of some of our consuls—that in virtue of the circular of the Secretary of the Treasury of October 30, as the Treasury Department could not collect duties on imports in California, their goods, though dutiable, could be imported without paying duty. I have held that this was not the construction proper to be given to the circular, but only that the law had not provided the means of collecting duties here, that law being still in force which prohibits certain goods being introduced into the United States, unless they pay duties as prescribed; that consequently no dutiable goods can be landed in California unless they shall have paid their duties elsewhere—the effect of which would be, that they could not be admitted at all from foreign ports.

Under the circumstances, which showed a very hard case, I thought it proper that the parties should be allowed to deposit the amount of duties and land the goods; but, lest this should be construed as giving them a right for the future, and as the president may think proper to put an end to this indulgence, I have addressed a circular to all our consuls on these seas, warning them of this possibility—a copy of which is inclosed.

I was directed, when coming here, by the Secretary of War, to do all I could to facilitate the arrival of the civil officers of government in Oregon, as the public service required their presence there. The steamer in which we came here could go no farther north, and there was no possible way of those gentlemen getting there, except on a small vessel about sailing, on which there were no accommodations.

Commodore Jones kindly sent carpenters from the fleet to put up some berths, and on General Adair's (the collector's) representation, that no bedding could be procured, I directed the quartermaster to issue him the necessary number of blankets for the voyage, and take his receipt for them. I respectfully ask that this may be approved, and the amount charged to General Adair. The quartermaster could not tell him the price of the blankets when he took them.

As the rainy season has ended, people are again repairing to the mines. New discoveries farther south are said to have been made; and it is now pretty certain that the whole slope of the Sierra Nevada, comprised within the head waters of the San Joaquin to the south and those of the Sacramento to the north, contains gold. These two rivers, forming, as it were, a bracket, join to enter the bay of San Francisco; and their tributaries from the east, in their beds, expose the deposits of gold as they descend from the mountains. It is on the banks and branches of these streams that adventurers are now at work; but some excavations elsewhere, to a depth equal to that worn by the creeks, have disclosed quantities similar to those most generally found. There appears to be a line parallel to the summit of the main ridge, and some distance down the slope, at which the product of gold is at its maximum; but whether this be from the quantity deposited, or from the different position as relates to the surface, or from the difficulty of working it, I have not the means of knowing.

The gold is found in small particles: the largest I have seen, but such are rare, weighs seventy-one ounces troy. The appearance invariably is as though it had been spurted up when melted through crevices and fissures in drops, which have often the form of the leaves and gravel on which they have fallen. I speak of this as an appearance, not as a theory or hypothesis. The extent ascertained within which gold is thus found is at least four hundred miles long by forty wide; in almost every part of which, where the surface is depressed by the beds of rivers, gold has been obtained without digging more than ten feet below the surface, and very seldom that much.

It is impossible to furnish any grounds for estimating the number of people engaged in mining, or the amount they have produced. Persons engaged in trading with the miners say they amount to about ten thousand, but I cannot say with what reason. They can better judge of the amount produced, which the lowest estimate places at $4,000,000. More than three thousand persons have been added to the miners up to this time,—chiefly from Mexico and South America.

When the mines were first discovered, all the ports of South America on the Pacific, and of the Sandwich islands, sent the merchandise collected and stored there to be sold here. They realized enormous profits, before any competition from our eastern States could meet them; and these goods were generally owned by European houses, who thus became possessed of the first fruits of the mines, which were shipped to Europe on their account; and it is thus that so little gold has reached the United States.

When the merchandise now on its way from our Atlantic States arrives, and is sold, the current will set that way; but the profits will be much diminished by competition, and still more by the enormous expenses here for labor, storage, &c. These are almost incredible; the ordinary wages for the poorest laborer is $6 per day; many receive $10.
