There is another feature in the existing law, which is not beneficial in its operation. It is that clause restricting the terms of leases to three years. To embark in mining operations with profit, it is necessary to sink shafts and galleries, build engines, and erect other necessary works, which are, in some degree, permanent in their nature, and require much time and expense in their completion. A considerable part of the period must, therefore, elapse before the mine can be put in a state for working; and no sooner is that done, and it begins to afford a profit, and promises a reward for the expense incurred, than the expiration of the lease throws all these works into the hands of some new adventurer, or more successful applicant. This prevents many from engaging in mining on the public lands, and especially those who would be best able to prosecute the business; and of the number who take leases, a great proportion continue to pursue the desultory method of mining in alluvial[20] ground, introduced at an early period by the French, but which is attended with very great uncertainty.
Improvements remain also to be introduced in regard to the processes of mining, the furnaces employed, and the method of raising the ore. Inseparable from this subject is the distribution of more enlarged practical and scientific views of mining and minerals generally, which might, in a great degree, be effected by the dissemination of practical treatises on the subject, or by the employment of experienced and skilful miners from Europe.
When such improvements shall be effected, with others to which it is not necessary here to advert--when miners are properly secured in the object of their pursuit, either by permanent purchases from government, or by leases for a long period of years--and when the facilities for transportation which that country is destined to afford, by the improved navigation of its streams, and by the introduction of turnpikes, roads, and bridges, are introduced, there is reason to conclude that the annual amount of lead produced will far surpass the proceeds of those mines under the present arrangement, and, indeed, it is impossible to calculate the extent to which it may be carried. It is, perhaps, a moderate estimate to say, that they are capable of being made to yield, by judicious management, six millions of pounds of lead per annum, and that they will furnish employment to three thousand hands.
