CLAYS OF OCEAN COUNTY. 485 



T uck ert on. — A gritty, mottled clay (Loc. 210) outcrops along 

 the road for a distance of 200 yards, one-half mile west of Tuck- 

 erton, and the section shows 5 feet of clay, but it is not worked at 

 present. The clay is quite dry and porous, and grades downward 

 into a mottled sand. In the laboratory when wet it (Lab. No>. 

 662) was not very plastic to the feel, although it had a tensile 

 strength of 173 pounds per square inch. It took 26.3 per cent, of 

 water to temper it, and the air shrinkage was 5.5 per cent. It 

 behaved as follows in burning :

Absorption, 13.16% 6.73% Low. 



Color red. red. deep red. 



The bricklet burned steel-hard at cone 1. 



It is possible that this clay might be available for more than 

 common brick, since it stands cone 9 without fusing, and burns 

 fairly dense and of good red color. Haulage from here to the 

 railroad would be along a fairly level road, or shipment by water 

 would be still easier. 



The following analysis of a clay from the land of Eayre Oli- 

 phant, near Tuckerton, is on file in the Geological Survey office '} 



Analysis of clay. Eayre Oliphant, Tuckerton. 



Silica (Si0 2 ), 58.15 



Alumina ( A1 2 3 ) , 27.37 



Ferric oxide (Fe^Os) , 4.83 



Water (H 2 0), 9.31 



Total, 99.66 



The analysis would indicate a red-burning clay. 



Two and one-half miles southwest of Tuckerton (Loc. 211) 

 there is a deposit of clay upon the Northridge property, which 

 was formerly used for common brick, and which is reported 

 to be of considerable extent, and to be 24 feet in thickness over at
