varable for plants, but is a little too sandy and crumbly. No impressions 
were found. There are sand pockets irregularly arranged in the clay. 
This is 200 yards above Electric road bridge. A cut just north of the 
bridge shows a good section of the reddish sand and gravel with clay 
pockets. It is flanked on the north by Lafayette. The cuts at Ft. Myer 
Heights, previously examined, are about the same and at the original 
locality on the wagon road I found the Archeon contact better than ever 
before. Just at the turn in the road and on the n.w. side the Archeon is 
immediately overlain with clays containing rounded stones Some of 
these were rotten and I got good specimens right at the contact

April 16 - Chinkapin Hollow is a ravine with a small stream that crosses 
the Leesburg pike less than half a mile n.e. of Fairfax Seminary. There, 
in comparing with Vick Mason & Wm Willoughby, I made a very 
important discovery. By the roadside near the top of the hill is what 
seems to be a typical Lafayette exposure, but nevertheless many of the 
pebbles were soft and decomposed. By the spring at the bottom of the 
valley ten feet of reddish sand with many clay balls are exposed. This is 
true Potomac. 100 yards down the stream is a fine section on the left 
side. It is chiefly sand, but there are clay veins, and in one of these a 
foot above the stream bed fossil plants were fund in abundance. They 
are chiefly ferns, but there are several species and there
