gain if He were won. For 't is the sun's own Sun I seek. The earth, they murmur, is the tomb That vainly sought his life to prison; Why grovel longer in its gloom? He is not here; He hath arisen. More life for me where He hath lain Hidden, while ye believed him dead, Than in cathedrals cold and vain, Built on loose sands of "It is said." My search is for the living gold, Him I desire who dwells recluse, And not his image, worn and old, Day-servant of our sordid use. If Him I find not, yet I find The ancient joy of cell and church, The glimpse, the surety undefined, The unquenched ardor of the search. Happier to chase a flying goal, Than to sit counting laurelled gains, To guess the Soul within the soul, Than to be lord of what remains. PHYSICAL HISTORY OF THE VALLEY OF THE AMAZONS. II. Major Coutinho and myself passed three days in the investigation of the Serra of Errere. We found it to consist wholly of the sandstone deposits described in my previous article, and to have exactly the same geological constitution. In short, the Serra of Monte Alegre, and of course all those connected with it on the northern side of the river, lie in the prolongation of the lower beds forming the banks of the river, their greater height being due simply to the fact that they have not been worn to the same low level. The opposite range of Santarem, which has the same general outline and character, shares, no doubt, the same geological structure. In one word, all these hills were formerly part of a continuous formation, and owe their present outline and their isolated position to a colossal denudation. The surface of the once unbroken strata, which in their original condition must have formed an immense plain covered by water, has been cut into ravines or carried away over large tracts, to a greater or less depth, leaving only such portions standing as from their hardness could resist the floods which swept over it. The longitudinal trend of these hills is to be ascribed to the direction of the current which caused the denudation, while their level summits are due to the regularity of the stratification. They are not all table-topped, however; among them are many of smaller size, in which the sides have been gradually worn down, producing a gently rounded surface. Of course, under the heavy tropical rains this denudation is
