Removal of the upper part of the north side of the arch by denudation. Fig. 67 represents the appearances which would thus be produced, and it will be seen that they very closely correspond with the present condition of the deposit, not excepting its thinning toward the surface. If this . ^ , , , , ... Ill Fig. 67.—Ideal representahon of the be the true explanation, it is probable Cause of the appearances at Albert that the sunken south side of the bed has not yet been reached in the ex- cavations. It might, however, in approaching it from above, show a succession of wedge-shaped included masses of rock or " horses," one of which I saw in the floor of the lowest level. On this view, also, the ' Jog ' or fault above described may be a lateral bend received by the bed in the original contortion of the strata; and at this point the straight fracture, producing the supposed downthrow, may have left the bed, and thus caused the appearance of the vein running in the former course of the bed along the line of fault, and also the greater regularity of the bed beyond the 'Jog.' This explanation is represented in Fig. ; As many readers of this work may be interested in the controver- sies respecting this mineral, I may shortly mention its physical and chemical properties, and the results at which I have arrived respecting its nature and origin. The substance has externally an appearance not dissimilar from the ordinary asphalt of commerce in its purest forms; but it is very much
