Nature . ears small excavations for clay havebeen made in a brick-yard east of Markyate Cell, but until thislast winter I have never seen any human work amongst theexcavated material. The implements occur in relaid contorteddrift, which has been washed in patches from higher ground,The implementiferous material only occurs here and there in thebrick-field ; it is a brown clay full of large stones, and rests upon abrick-earth of much greater age, probably glacial, which in turnrests on Lower Chalk. The implementiferous clay is on thesurface, and is never more than two feet deep. The pit is 108feet above the Ver, and 547 feet above the Ordnance datum. Oi>the hills to the north, and removed from the water-shed uf theVer, implements occur at 595 feet. I have lately found six Palceolithic implements in the valley ofthe \er at Markyate Street, all above the average in size andweight ; they are faintly ochreous and slightly abraded. Theexample illustrated to one-half the actual size—1673 in my I. Pala;olilhic implement from ihe valley of the Ver. One-half actual siic collection—weighs i lb. 63 ozs., two others weigh I lb. i , others i lb 4 ozs. and I lb. 4J ozs. With these implementswere numerous large cores and large blocks of flint, from whicha flake or two had been struck. These were alxandoned by meas too heavy for convenient carriage. Only one flake has cometo hand ; in fact, no stones as small as ordinary flakes are in thematerial. I have found a few Palnrolithic flakes one and a halfmiles nearer St. .Vlbans, in the same river valley, north ofFriars Wash. Twenty-one years have now passed since I first directedattention to the ;oIithic implements found on the hill-lopsof North Herts [[oKr. Anth. ItistitiiU, vol, viii., iS7S>. Sincethat time I have greatly extended my observations on these hills,but no evidence w hatever has been seen by me indicative of agreater antiquity than post-glacial.
