that is, the bird would have stood ten feet or over in height. 

 Similar monsters among the birds occur in the Santa Cruz. 

 With these are also smaller running birds, and also flying 

 ^ forms, some no larger than a robin. But it is very unusual 



to find many bird bones in a land deposit; so that from 

 the presence of over twenty finds of birds we must conclude 

 that they were very abundant among the creatures of that 

 time. 



The large numbers of shells will offer little new, but are 

 of primary importance in determining the ages of the rest 

 of the material. 



The collection of Indian implements, while not large and 

 picked up as a side matter, offers several features which 

 are of general interest, like the novel types of hammers, 

 and the similarity in the workmanship of the North Ameri- 

 can types of Indians. 



It will require a year of work on the part of several in- 

 dividuals to complete the study of the material, and as 

 soon as it is done the final results and descriptions of new 

 forms will be brought out as the second volume of this 

 report.
