While there is considerable literature on the cliff-dwellings of the Mesa Verde, individual ruins have not been exhaustively described. Much less has been published on Spruce-tree House than on Cliff Palace, which latter ruin, being the largest, has attracted more attention than any other in the Park. As every cliff-house has its peculiar architectural features it is well in describing these buildings to refer to the ruins by names. This individuality in architecture pertains likewise to specimens, the majority of which in museums unfortunately are labeled merely "Mancos" or "Mesa Verde." A large number of these objects probably came from Spruce-tree House and Cliff Palace, but it is now impossible to determine their exact derivation. The first extended account of Cliff Palace, accompanied with illustrations, which is worthy of special mention, was published by Mr. F. H. Chapin, and so far as priority of publication is concerned he may be regarded as the first to make Cliff Palace known to the scientific world. Almost simultaneously with his article there appeared an account of the ruin by Doctor Birdsall, followed shortly by the superbly illustrated memoir of Baron Gustav Nordenskiöld. All these writers adopt the name Cliff Palace, which apparently was first given to the ruin by Richard Wetherill, one of the claimants for its discovery. Nordenskiöld's work contains practically all that was known about Cliff Palace up to the beginning of the summer's field work herein described. Mr. Chapin[6] thus referred to Cliff Palace in a paper read before The Appalachian Mountain Club on February 13, 1890: [Footnote 6: _Appalachia_, VI, 28-30, May, 1890, Boston, 1892.]
