Our correspondent at Washington writes us under date of the 8th inst. as follows:
Mr. H.J. Graham, the first elected delegate from Pike's Peak under the popular organization, arrived here on the 2d instant, and has communicated valuable infomration to members relative to this interesting region. Mr. Graham thinks that about $15,000 in gold had been taken out and sent to the States.The mining parties arrived late in the season, and were not able to do more than to make surface explorations before it became necessary for them to prepare shelters for the winter. His general conclusion from what he saw and heard is that for a space of one hundred miles north and south the country would supply gold at a paying rate per hand. The miners had no machinery, and were compelled to confine their operations to washing dirt in pans. There was plenty of water and sufficiency of cotton wood and pine for all necessary purposes.The settlers had begun to get out lumber with whip saws the day before he left.Coal was reported within convenient distance of Auraria by the mountaineers. It was thought that the country would prove well adapted to the production of wheat, as well as to the rearing of sheep.
Mr. Otero, representative from New Mexico, says the boundaries proposed by Mr. Colfax's bill include the best part of this territory for agricultarl purposes, but he assented to the very practical remark of Mr. Graham, that there is land enough for all.
