In the southern room on the first floor of the Sydney Museum is a large collection of bones from the Wellington and other caves. These remains have been collected during the last four or five years under the direction of Mr. Ramsay, the curator. They are chiefly the bones of marsupials. There are not among them any fossil remains which indicate the presence of man in Australia at any very remote period. Some of the principal bones are those of extinct marsupials, and are important from a scientific point of view. They include bones of the following animals (species extant) found in the Wellington caves:--The thylacinus (Tasmanian tiger), sarcophilus (Tasmanian devil), mastacomys (a rodent), hapalotis albipes, and mus lineatus (New South Wales). Other important fossil remains in the Museum are those of the thylacoleo (two species), diprotodon, procoptodon, protemnodon, palorchestes, macropus titan, nototherium, phascolomys. There are not in the Sydney Museum any bones from the Jenolan Caves--which, however, contain many interesting remains of the animal world,--because the search for them would involve the destruction of attractive features. For these reasons attention was given to the Wellington Caves, whose beauties were not likely to receive further disfiguration than they have already suffered. From the Wallaby Bone Cave the visitor returns to the Fossil Bone Cave, and ascends a wire ladder which is about to be replaced by an iron staircase. As he mounts this wire-rope ladder, which is 76 feet long and not "stayed," he feels the necessity for some better means of communication. From the top to the Cathedral is about 25 yards south-east. A large portion of the cave north-west from this point has not been explored. There are five or six different branches, one of which runs out to daylight at a small aperture (14 inches by 18 inches) over the rise of the water below the Grand Archway and the Devil's Coach House. The distance from here through the Cathedral to the entrance gate is about 70 yards, up two flights of steps. There is a gradual ascent to the steps, and the final flight of 41 brings the excursionist to the gate and to the sunshine. He will be glad to rest awhile before entering the Imperial Cave, which is the grandest of them all. CHAPTER XIV. THE IMPERIAL CAVE.
