Dear Sir: I have long known Mr. Richard Temple, and take great pleasure in commending him to you and in stating that his statements can be implicitly relied upon. I thought it might be of importance to the government to ascertain the character of the mines of which he speaks. Very respectfully, your obedient servant, O. O. HOWARD, Brevet Major General U. S. A. Admiral Davis. The discovery of coal on the Isthmus of Panama. The existence of coal on the Isthmus of Panama has always been a subject of great interest, both to science and commerce. About three years since Captain Daniel George, a citizen of the State of Panama, discovered a large deposit of excellent semi-bituminous coal on the Rio Indio, (the river of the Indians,) in the territory of the department of Code, district of Penonome, sovereign State of Panama. Extensive grants of land were made to Captain George by the State of Panama, which he has legally transformed to Richard Temple, the present proprietor. 36 INTEROCEANIC COMMUNICATION AT AMERICAN ISTHMUS. DESCRIPTION OF THE MINES. 1. Uvero. — The coal at this mine crops out in different places and in different forms. The well or shaft was dug here near the base of the hill, which is about one hundred feet high, and lightly wooded. The dip of the seam at the well seems perpendicular 5 while on the opposite side of the hill it appears again, and there the seam runs horizontally. 2. Iaboncillo. — This mine is described as a wonderful deposit of coal. The vein crops out on the banks of the Rio Indio, w r here it rises about thirty feet, and extends up and down the stream for about three hundred yards. The canoe can be put close alongside. The hill on which the well was dug rises about sixty feet from the banks of the river. 3. JEsterial. — This mine is situated on the bank of a small stream that flows into the River Esterial, which also empties into the Rio Indio. Near the small stream, where the coal is found there rises a hill about two hundred feet high. The dip of the vein is about 60°, the thickness of the seam about six feet. The coal as seen on the opposite side of the stream seems to run in the direction of Guinea, with the dip of 00 °. The land is quite level between these two mines. 4. Guinea. — This mine is at the side of a thinly- wooded hill, of about fifty or sixty feet high. The vein appears about nine feet thick, with but little dip, being nearly horizontal. The general course runs west. THE MINES IN GENERAL. The foregoing descriptions were given by Captain George from mem- ory. I should judge from them and from what lie said otherwise, that what has been granted to him as u The Rio Indio coal mine,” consisting, as expressed in the grant, of four distinct veins or mines, is, in reality, but a single underlying stratum thrown up into different forms by some great internal movement in former years. That there are immense coal deposits there seems evident proof from the statements of all who have been there. The freedom with which some of the larger and better specimens burn leads to the reasonable conclusion that the coal is of a valuable quality, that is, when taken from such depths as to secure fair specimens. MODES OF COMMUNICATION. 1. Road f rom Penonome to Aspimvall. — There is a road from the inte- rior city of Penonome to Aspinwall, passing by the mines. It is a cattle road, chiefly used in summer. From the mines to Penonome is a two- days 7 ride on mules; and from the mines to Aspinwall, one day and a half. 2. Down the Rio Indio. — The streams from the mines fall into the Rio Indio. This is a river, in ordinary water, of sufficient size for large canoes, with a heavy current for nine months of the year, when full. The port is narrow and only adapted for light-draught vessels. A 11 engi- neer alone could decide whether the outlet could be made available or not. My own opinion is that the river can be made available for at least a portion of the year, but the port lies on the Atlantic side. 3. By the way of Chagres . — From the mines to Gatlin, where one strikes the railroad, is a day’s journey. Flat-bottom boats can go down during nine months of the year. The country is everywhere heavily timbered. Gatlin would be the cheapest and best temporary outlet. 4 . By the ivay of Chorrera. — There is no open road to Chorrera, which INTEROCEANIC COMMUNICATION AT AMERICAN ISTHMUS. 37 is probably the nearest point on the Pacific coast; but Indians speak of going there through the forest in two days on foot. There is a large stream that runs from the direction of the mines capable of floating small steamers. Of this, however, nothing can be satisfactorily ascer- tained until a complete survey be made. In January, February, and March, Indians could be sent through the forest and the best information be obtained. Population . — The entire population in the neighborhood of the mines consists of Indians, (Choices.) They are quiet, peaceable, and industri- ous, quite unlike the worthless population of the coast. They number, I should think, about three thousand. Wages . — They would probably ask from sixty cents to a dollar per day, and find themselves. Living .— Living is very cheap when the productions of the country are used. There is good beef, with fruits and vegetables in immense variety. Climate .— The climate is much superior to the coast, Seasons . — There are about eight months of the year called rainy months, and four usually without rain, H, Ex, Doc, 113 - — A O
