536 HISTORY OF PASADENA. 



Another cog-wheel, of close-grained brown ferruginous grit rock ; same 

 size as the first, but having only 9 cogs, and they more irregular in size and 

 imperfectly made. A segment with four cogs is broken away. The creases 

 are small and shallow, and some of them run aslant. A rude, unskilled 

 effort at wheel making. [The purpose of these peculiar wheels is not well 

 established. They have been called by different names, as sun wheel, rose 

 wheel, cog wheel, corrugated disc, radiate stone, gaming stone, etc. My 

 own theory is this : The sun was the deity or day-god to all primitive 

 tribes of mankind, and these radiate stones were a rude attempt to make an 

 emblem or symbol of the sun. And after this they would readily fall into 

 use for gaming purposes or " lucky stones " or " chaims," and come to be 

 greatly prized.] 



Mr. McQuilling had also found there two irregular small fragments of 

 unworked impure flint, but no flint chips, or arrowheads, or anything to in- 

 dicate any use made of flint by these people. Besides this, he found about 

 a half-ounce fragment of yellow ochre. 



List of specimens found by J. W. Sedwick, city engineer, while re-ex- 

 cavating, embanking and cementing work was in progress there in 1891-92 : 



One flattened and two ovoid hand-stones for grinding on a metate. 

 Material, syenite. 



One double-surface rounded-sides mealing stone, of gray syenite ; 4^ 

 in. long, 2^ in. wide, and yS/i in. circumference. Weight about i}{ lbs., 

 and much worn. 



One ovo-oblong rubbing stone, of white feldspar, smooth polished ; 3^ 

 in. long, 5^ inches around midway, and 9^ in, around lengthwise. 



One spheroidal rubbing stone of bluish syenite, about one pound 

 weight, and varying from S'/s. to 9)^ in. in circumference. Artificial wear 

 only in one place. This was a naturally rounded pebble or small cobble- 

 stone which they had utilized. 



Found by Master Clifford Wood (1892), a neatly -shaped, small, semi- 

 oval, shallow-dished metate, of grayish syenite ; 5^ in. diam. at bilge, 3}^ 

 in. diam. of dish rim, and 3^ in. thick from bottom of dish to base of the 

 stone. This was probably used to grind ochre for face paint. 



T/te Throop Museum Collection. 



(Authenticated specimens procured by Dr. Reid specially for permanent deposit in the Throop Museum.) 



One discoidal stone of coarse-grained syenite; 5)^ in. diam., 2^ in. 

 thick. The form is well wrought out, although no part of the disk is worn 

 or polished — hence it was not used for a rubbing stone or a grinder. Its 

 most probable use was for some kind of game or pastime by rolling it on the 

 ground. This specimen was found in 1874, and donated by Col. Jabez Ban- 

 bury. 



One six-toothed cog-wheel or sun-stone (?) of fine-grained greenish 

 porphyritic clinkstone; 4 in. diam., i^ in. thick. Indentations i^ in. 

 across outer opening, and )^ in. deep. Found by Wm. Davy while repair- 

 ing a leak in the reservoir in 1888, and donated. [For further account of 

 this class of wheels, see under " McQuilling collection," above.] 



One large shallow-dished metate, of coarse-grained gray syenite — a 

 fine specimen ; 21 in. long, 14 in. wide, 36 in. girth, 49 in. around length- 

 wise, and 50 or 60 pounds weight. Found and donated by John Showalter. 

 [This specimen was plowed up several rods down the eastern slope of Reser- 

 voir Hill, two feet below the surface, while grading Vernon Avenue near
