At Guayabalito the daily yield inthe winter (dry) season, with a small force of men, runs from 44 to102 ounces; at La Llave it has run from 261^ to 29!;. ounces; atCaracoli, from 58 to 73ij ; at Xaranjal, 15 ; at Oralito, 73)^2 ; and,at Socorro Megaron, as much as 132. At San Basilio, in two weekswork, 764 ounces of gold were taken out in the winter of 1886, and atSan Jose 588 ounces were extracted in the working-season of 1885. An English engineer of some repute examined and reported on. ,RCE RIVER, NEAR MEDEIXIN. 988 THE GOLD-FIELDS OF THE FORCE RIVER. the richness of the Force river some years since ; he estimated that theriver contained gold in the proportion of 143V ounces per superficialsquare yard, and that in the lower fifty-mile reach of the river, afterits junction with the Nechi, there were more than 4,000 tons of gold ! The writer of this paper noticed, during his connection with thesurveys of the Intercontinental Railway, the richness of some of theForce bars, and he has recently been conducting some examinationsand tests which show results in keeping with those above described. At one place, where the bar had a formation of about six feet ofloose sand (decomposed granite) mixed with boulders, and belowthis another formation of gravel, sand, and boulders, the upperstratum showed, from the grass roots down, an average of $6 per ? l^^^^v^^^^HHta 1 i^fei 1 I ^?^ 1 ^H| —^ -, :-- -^ ? iHI^H^HBI A PART OF THE FORCE WHERE B
