The South Fork I did not visit, but the photographs show that it possesses scenery as romantic as the other branches of the canyon. It is interesting to notice that these enormous waterfalls in the Merced Canyon have scarcely an indentation on this most hard rock,--a fact probably indicating that they have not existed a great length of time. The comparative absence of detritus in the upper part of the main valley would seem to show the action of water and ice, pressing the debris into the lower portion, where more of it is found. There are, too (as was discovered by Mr. King), something which may be called lateral moraines, and perhaps a terminal moraine in the middle of the canyon, so that it seems not improbable, though there is no absolute evidence, that in a comparatively recent period glaciers existed in the upper part, and a lake in the body of the Yosemite Canyon, the descent of the whole valley, it must be remembered, being only fifty feet during some eight miles. A SPORTSMAN'S EXPERIENCE IN MEXICO. SIR ROSE LAMBERT PRICE. [Major Price, whose hunting adventures seem to have extended from Terra del Fuego to the northern boundary of the United States, gives us, in his "Sport and Travel; or, The Two Americas," a record full of incident and observation. From his greatly varied hunting experience we select a description of the pursuit of game in the vicinity of Acupulco, Mexico, which is of interest as showing the conditions of animal and vegetable life in that region.] The day after our arrival, H---- and myself, getting mules and a guide, started for Pira de la Questa, a small Indian village about twelve miles from Acupulco, and situated near the extremity of a large lagoon, some thirty miles in circumference, which we were informed was full of wild fowl. Over many a rough road and in many lands have I ridden, but never did I travel a highway like unto this. The path ran over the mountains through a thick forest, and more resembled the bed of a water-course than an actually connected route. Nothing but mules, whose cat-like propensities enable them to overcome apparently insurmountable difficulties, could possibly have done the journey. In places the path was so narrow that two of these animals were unable to pass abreast, so that one would be obliged to go back into a convenient corner, or scramble up a bank, to permit the other to go by.
