6 were the first to be worked, and the return of gold began to assume import- ant dimensions. “Before the close of the working season in 1858, some of the adven- turers who had come overland from the south had pushed onward in face of extraordinary difficulties—resulting not alone from the roughness of the country itself but combined with the want of supplies and occasional overt hostility of the Indians—as far as Fountain, a short distance above Lillooet on the Fraser, and by the line of the Thompson to Tranquille river on Kamloops lake. In the following year a renewed advance brought a number of miners to Quesnel river, and in 1860 rich diggings were found at the forks of the river and over 600 whites were at work on its length, while Antler creek was discovered and some work done upon it by a few score men—thus fairly entered on the extremely rich central region of © Cariboo. “The theory formed by the miners who first worked the fine ‘flour’ gold of the Fraser below Yale was that this gold had its origin in richer deposits toward the sources of the great river, and though this theory was only partly correct as regards the origin of these particular deposits, it none the less served as the impelling force which led to the opening up of Cariboo district. “In 1861, Williams and Lightning creeks, Cariboo, the two most celebrated in the annals of British Columbia placer-mining, were dis- covered, and in this and the following year most of the other rich creeks in Cariboo became known. The first gleanings from the old Cariboo stream-courses were notable. It is estimated that gold to the value of $2,000,000 had been got out by a population not exceeding fifteen hundred before the end of 1861. In consequence of those finds a second important migration of miners and others towards the province commenced before the close of 1861, which continued in greater or less volume until about 1864.
