CINCINNATI, HAMILTON, AND DAYTON RAILROAD.

The following statement of the monthly earnings of the Cincinnati, Hamilton, and Dayton Railroad, for the first year of its operations, has been obtained from the Secretary of the company. It will be seen that nearly all the business of this road so far is local; and that has nearly doubled within the year.

The earnings of October, 1852, were over thirty thousand dollars. The travel during the past two weeks, however, has somewhat fallen off, owing, doubtless, in a great measure to unpleasant weather. The earnings of the month will probably not vary

much from the last.

RAILROAD FREIGHTS BETWEEN ALBANY AND BUFFALO.

The central line of railroads between Albany and Buffalo, have adopted the following schedule of rates of transportation of property between Albany and the several cities on the route :

TO FREEMAN HUNT, Editor of the Merchants' Magazine :—

My article, published in the December number of the Merchants' Magazine, contained the leading historical facts connected with the Southampton and Easthampton Lead Mines, and referred to the Spathic Iron, or silver-steel mine, at Roxbury, Litchfield County, Connecticut, and also to a lead mine now worked by Dr. Frankfort, at Middleton, (instead of Norwich,) Connecticut, stating that it was early worked by Sampson Simson, Col. James, and others. These particulars I propose to make the basis of further remarks at some future period.

I now propose to give you a short statement, embodying all the geographical, geological, and mineralogical facts, relating to the Hampton mines, with an analysis of thirteen specimens of ore and rock taken from various places in the old shaft, which we have recently emptied of water.

The South and East Hampton mines are located in Hampshire County, in the State of Massachusetts, 155 miles from New York by railroad, eight miles south-west of Northampton village, and about three miles north of the proposed depot on the canal, or air-line railroad, now in course of construction. The proprietors of the mines have purchased the lands on both sides of the Manhan River, along the course of the vein. There are about 520 acres, consisting of farming and wood land; upon these it is estimated there are more than 20,000 cords of wood, and an abundance of timber for building purposes. The vein, where it crosses the Manhan River, has thrown up a dyke to the hight of twenty feet, forming a portion of a substantial dam. From this point the proprietors propose to conduct a portion of the water along the west bank of the river to the mouth of the 1,240 feet adit, and use it by means of an overshot or breast wheel, having obtained a fall of 35 feet. To this wheel they propose to attach flat rods, extending along and through the adit to the engine shaft, sunk on the course of the vein, for the purpose of raising the ore and delivering it at the ore-house at the mouth of the adit, in which the stamps, separator, and elevators are erected. Near this they propose to erect smelting and cupelling furnaces, thereby saving the expense and time in erecting the engine, the cost of fuel, repairs, and engineers to run it.

The first geological survey of this mine was made by Colonel James, Royal Engineer, and Solomon Simpson, Esq., the father of the Hon. Sampson Simpson, of 42 Warren-street, in the city of New York. They were gentlemen whose scientific attainments are unsurpassed at the present day, as their papers give abundant testimony. This survey was made in the spring of 1765. Although I do not find their report itself, yet I find abundant proof that they were highly gratified with their prospects and the geological evidences there discovered by them.

The next examination, I am inclined to believe, was made by Professors Mead and Eaton. The latter gentleman has left a record of the curious geological changes passed through by the miners during the thirteen years they were engaged in driving the adit level, with a description of the various rocks, stratification, etc.

In the year 1810, Professor Benjamin Silliman made an examination of these mines
