residue, on being deposited between the grains of sand, the particles of 
gravel and the pebbles cemented them together into the solid rock. 
The character of the beds of material uuderlying the consolidated por- 
tions is such that capillary action was not only possible but highly prob- 
able. The greater abundance and the grenter thickness of the indurated 
beds on the side of the gravel bar nearest the creek indicates that its 
waters were largely responsible for the presence of the cementing ma- 
terials. 
In explanation of the formation in places of material resembling sta- 
lagmite, it is probable that surface waters fowing over or through the more 
or less consolidated rock redissolved a part of the cementing material, and 
when such waters reached the surface of the soil or rock at a lower level 
they were evaporated and the calcium carbonate was again deposited in 
the form mentioned.
