protected by a lantern. The entire floor of the Waterfall Room is covered with 

 beautiful water formations, resembling the figures on a carpet, but standing 

 out in relief. The walls are similarly covered, the formations looking like pails, 

 baskets, etc. In front of the fall are jug-shaped basins, varying in depth from 

 one to two and a half feet, and in width from six inches to three feet, with open- 

 ings only big enough for the insertion of the hand. The water streams in them, 

 and probably passes out again through small cracks ; which matter, however, has 

 not yet been ascertained, nor what becomes of the water. These basins contain 

 white, soft, blind, toothless lizards, from two to six inches in length. The roar 

 of the waterfall, and of other falls below not yet reached, is such as to render 

 conversation in any portion of the room impracticable. 



At the opposite corner of the crescent is an ascending passage about four 

 feet wide. The roof of this passage is a continuation of that of the Waterfall 

 Room. The floor is of red clay, very slippery, into which steps must be cut, as 

 the angle is 45°. The passage is nearly straight and about 100 feet long. It 

 ends in a room sixty feet above the level of the floor of the Waterfall Room. 

 This room, which one enters by a turn to the left, is about ten feet high. It con- 

 tains one large spring and a cluster of smaller ones. In a backward direction it 

 is connected by a passage about forty feet long and four in height and width, 

 with a similar room, also containing springs. This second room is, by a similar 

 passage, about twenty feet long, connected with a third room of the same kind. 

 The two first rooms are about of a size, but the third is smaller. The third room 

 contains the head of the waterfall; and the springs in the rooms last mentioned 

 furnish a portion of the water. These rooms and the connecting passages are 

 together between 300 and 400 feet long. The rooms are about thirty-five feet in 

 width. From the first and second rooms, passages lead to other rooms beyond, 

 but these have not been explored. Water also flows from those unknown 

 farther rooms. The waterfall is fed, not only by the springs above described, 

 but also by a swift, shallow stream, about thirty feet wide, coming through a low 

 canon. This canon has been ascended for a distance of about 700 feet, and 

 might be farther explored. The entrances to ten passages, all but one ascending, 

 and with water running through them, were passed. Half of these passages are 

 on one side, and the balance on the other, of the canon, at very irregular inter- 

 vals. They have not been examined, except the second to the left, which de- 

 scends and is dry. That passage is about eight feet wide and four feet in height. 

 Its entrance is dammed by rock and water formations. The passage gradually 

 increases in height, until it reaches ten feet. It winds and is about 200 feet long. 

 It opens on a semicircular room. The descent to that room is very slight. The 

 room is over sixty feet high; greatest width twenty feet; length of outer curve 

 250 feet. The walls are emery rock and red clay; preponderance of red clay. 

 About one half of the floor is covered with a thick layer of fine guano. The uncov- 

 ered balance shows the red clay. The entrance is at one end. At the opposite 

 end the wall does not go clear to the top, but runs up to a height of thirty feet. 

 It is a heavy bank of red clay, studded all over with pointed pieces of mica, of
