Further down the banks are much higher (20 feet) consisting chiefly of sand beautifully cross bedded or with pockets, lenses and various irregularities, and of different colors. Pretty high up in the largest exposure is a thin vein of fine buff or pinkish clay containing abundant remains of a Sequoia and many male aments, also seeds and other parts. Here also I found a shell.
Near Convalescent Camp on the road to Arlington just this side (north) of the little swamp where Henshaw and I botanized, is a sand pit showing 10 feet of light colored Kaolinic sand The whole is Potomac.

Nos. 1 & 2 of same section and square across, just below the third of the small trees set out on the hill above. Hour 10-30. In the first, I was in the unit & the sun was shining, but not on the exposure. In the second he was the unit & the sun was clouded.

The fair (No. 4) was rather long exposure,
