in broken fragments of leaves, twigs, limbs and trunks of trees as 

 well as of seeds and cones. These all appear as debris and nothing 

 is in situ. The larger amount of the material seems to be that of 

 live-oak, cedar and pine. The species of which have not been worked 

 out. 



These bones and vegetable remains have been thrown together in 

 such confusion as to render the removal of them very tedious and 

 difficult. The bones are so mingled that two consecutive ones are 

 rarely found together. But sloth and tiger, mastodon and wolf, bird 

 and beast, in fact some part of mine than twenty animals may be 

 found in a few cubic feet of space. 



To remove these, requires very little use of pick and shovel, but 

 a great deal of painstaking labor with small tools, such as a garden 

 trowel, flat file or a crooked wire. In this way often much less than 

 a. spoonful of the tarry matrix is removed at one time. Then too, 

 while attempting to lift a certain desirable bone, a dozen others

crossing it in one direction and another, (Figures :;. 4) must first be 

 most carefully taken away. This is very trying on one's patience, 

 for it is not uncommon to begin in the morning on a certain bone 

 and by night be, apparently farther away from it. On one occasion 

 a. member of the Board of Education came from the city to witness 

 the digging, and decided to see a certain camel bone, plainly in 

 sight, taken out. The digging for this bone began at 9 a. m. and 

 it was exactly 2:30 p. m. when the coveted prize was placed in 

 his hands.
