the Pacific. The trip may be made in four or five days from Carta­gena, allowing for touching at way stations and other detentions.
Properly managed, there appears to be a broad field for American capital and enterprise in the mining districts of Colombia. The inhabitants of those districts have merely gathered from the surface of the soil an infinitesimal fraction of the mineral wealth of the Republic. The alluvial placer deposits are in the hands of small miners, who spend a portion of the week in washing the gold-plati­num sands and clay, another part in their corn and garden patches, and the rest of the week in placid enjoyment of life. It is said that no effort has ever been made to discover platinum in ore bodies or vein deposits nor, so far as can be learned, has it ever been found in quartz, even in the shape of float.
Concerning the location of the best platinum mines of Colombia, Mr. Lucindo Posso, of Cartagena, an exporter of the metal, gave Consul Manning the following information:
The richest mines are on the Condoto, the Opagado, and the Tamanal, all branches of the San Juan River. In the province of Atrato there is only one small district, Negua, from which platinum is taken. Some new mines have lately been discovered in Nobitu which promise to be very rich, and a company of French capitalists has recently made very large purchases in the platinum district. This company is headed by Albert L. De Lantreppe, of London, England, and it is soon to send competent engineers to make a careful study of the region and especially of the properties which have fallen into its hands. Gen. Ramon Buendia, a Colombian, has bought a great quantity of mineral lands in Condoto and Nobitu. There is yet a great expanse of country there rich in minerals of all kinds where platinum must exist in goodly quantities yet unprospected and virgin. There is certainly a great field for the prospector and miner there.
Judging by the statements of various exporters in Cartagena, there is reason to believe that a great deal of the platinum and gold of the Cauca is shipped out through Buenaventura and via Panama, and that it is divided between France and the United States. It seems that France and other European countries received the larger portion up to a short time since, but now there seems to be a tendency to forward the bulk of the output to the United States, where the demand has increased wonderfully and where the price is satisfactory.
Through the courtesy of Senor Don Washington Mendez, of Car­tagena, Mr. Manning has been enabled to make public the following extract from a report made by the former in January last to a firm in Paris, which report is very valuable as giving essential information regarding the character of the country in which the mines are located, its healthfulness (or unhealthfulness), etc.:
Platinum is found in its greatest abundance in the region of Choco, Barbacoas. and San Juan, and especially in the latter. The district is easily accessible by steam­boats to Quibdo by way of Cartagena in four and five days of travel, including in this time the detentions in the ports. The principal places are Quibdo and San Pablo, especially Quibdo, which is the capital of the province of this name.
There are no mines in exploitation. The mineral which they export from here is that encountered in the bottom of the canyons of the rivers in the form of powder (dust) and in the exploitation of the bars which contain it. The work is of a very primitive mode, like that in practice in ancient times. Up to the present the in­dolence of the people has been so great that they have not discovered the first ledge which would carry platinum, because they have made no serious study or scientific exploration. Labor is abundant.
It is not possible to find anyone willing to contract a certain quantity of platinum, no one having, as I have said, made serious explorations and there being no acquired rights. In order to understand the situation properly, it would be necessary at the beginning to send a mining engineer- to study the ground. However, the enormous
