Comparing the results by the number of successful days first, we may say, that for gold-producing, the sub-metamorphic rocks are to the metamorphic as (100—13-6=) 86-4 to (100—66=) 34=2-5 : 1; comparing by daily average, the proportions become .49 : .16=q. p. 3:1. We may therefore conclude that the sub-meta-morphics are between two-and-a-half and three times as productive of gold as the metamorphics, so that as the gold-washers only find a subsistence from washing in the sub-metamorphic area, it is obvious that it would not pay them to work in the metamorphics. 1 2
