150 | Feb. 25, This fall is often known as Hartford, Linn Co. 
2:45 P. M. Hartford is, however, a hundred miles distant 
and not in Linn Co. The name seems to have 
been applied because one of the first published 
letters describing the fall was dated from 
Hartford. As the fall took place only nine 
miles from Marion and this is the nearest large 
town as well as the county-seat, it seems to be 
the best name by which to designate the fall. 
Stone. Veined white chondrite, Cwa. Mass 
with crust. The crust, thick and dull black, is 
intersected by numerous cracks. Interior 
pearl-gray, abounding in minute iron grains. 
Delicate lines of fracture, which traverse the

slickensided surfaces. Cat. No., 255.
