FROM PHILADELPHIA 163 



of every size but with no indications of a water-polish- 

 ing. This sort of stone, that is, appears at the surface 

 and covers the backs of the mountain. But near the 

 Delaware Gap, about Easton, mill-stones are quarried, 

 of a rough and sharp-grained quartzose sort of stone, 

 which with other circumstances inclines me to think 

 that this or a similar stone lies beneath the first. On 

 the north-western slope of the mountain the red soil 

 appears again ; and beneath it patches of a fine brown 

 earth very like umber, in every case surrounded by a 

 paler earth. This would certainly make a good dye- 

 earth. 



The Kittatiny is crossed without especial difficulty 

 and in the next valley one comes to Eckard's house, 

 3-4 miles from Heller's. The man who lived there 

 had the place for a third of the nett income from all 

 produce ; but there is the stipulation that every year 

 six acres of land shall be cleared of wood and made 

 ploughable that is to say, four acres of upland and 

 two of bottoms. These are hard conditions. 



Beyond this house the next mountain (much lower 

 than the Blue Mountain, but running in the same di- 

 rection) contains a blue limestone; the darker the color 

 the better it is held to be. Along the road over this 

 hill no limestone comes to the surface, only sandstone ; 

 with it is a horn-stone or agate which in color and ex- 

 terior appearance resembles the limestone but strikes 

 fire on steel. 



Leaving Eckardt's we got out of the straight road 

 which we should have followed to Brinker's Mill, and 

 bore to the right, in this way passing by several plan- 

 tations which we should not have looked for here. 

 These lie scattered in the forest-vallevs and are settled
