consist of shells, detritus, santl and ve.t^etable matter, and to be 

 everywhere more or less consolidated to the dejjth of from six to 

 eighteen inches. The consolidation was such that in many places it 

 was very hard to penetrate the crust with an ordinary mattock. 

 Within this crust, on Ijreaking" parts of it off and turning- them over, 

 were found numerous human bones, including some more or less 

 defective skulls. Beneath the crust was white sand, which also con- 

 tained many bones, with a few Indian ornaments and fragments of 

 pottery. The consolidated crust differed in com]:»osition. For the 

 larger part it w^as coquina, of just about such a composition as beach 

 accumulations along the sea ; but in other ])laces the solidified part 

 consisted almost entirely of white sand, while in still others it w^as 

 a dark concretionary mass enclosing' shells, sand and vegetable matter, 

 besides the bones. The human bones, though evidently more or less 

 changed, were not yet petrified ; and the mound as a whole appears 

 to have no claim to antiquity greater than perhaps a few hundred 

 years ; but its surface offers a fine example of what favorable con- 

 ditions can accomplish in no great space of time in the way of con- 

 solidation and inclusion in rock of human remains. 



A series of interesting specimens from the mound are now on 

 exhibition in the U. S. National Museum.

EXPEDITKIN TO BORNEO AND CELEBES 

 In the report on explorations during 191 5 (Smithsonian Misc. 

 Coll., Vol. 66, Xo. 3, pj). 41-44), I said that Dr. Abbott had decided 

 to continue the work begun in Celebes by Mr. H. C. Raven, and 

 that Mr. Raven had spent part of the summer of 191 5 in Washington 

 assembling his outfit. The return journey began late in October. 

 On January 4, 1916 Mr. Raven arrived at Menado, Celebes. His 

 work from January to the end of August was in the northeastern 

 part of the island. Some idea of the conditions under which it has 

 been carried on is given by the photographs here reproduced, and 

 by the following passages from letters : 



Menado, Celebes, January 4, 1916. 



I arrived here this morning and am very glad to have finished my journey. 

 As yet I have not definitely planned my route, but it will probably be best to 

 start on the extreme end of the peninsula, somewhere in the mountain? near 

 Likoepang and work along toward Gorontalo. 



LiKOEPANG, Celebes, March 9, 1916. 



I have been collecting licre and at a place a few miles southeast of here since 

 January 12th. I am now living in the kampong, but my other camp was in 

 heavy forest more than two miles from any home or clearing. The natives call 

 the former place " Teteamoet " and the forest there is the finest I have seen in
