It is interesting to note that these ancient flint workings, in which we find the best examples of transitional forms, have both of them some suggestion of remote age. The pits from which the flint was procured at Cissbury are covered by the ramparts of an ancient British camp and the ground near Grimes Graves has yielded Palaeolithic implements _in situ_ in small rain-wash hollows close by--as seen near "Botany Bay." Palaeolithic man came into this area sometime after the uplift of East Anglia out of the Glacial Sea and was here through the period of denudation and formation of river terraces which ensued and the age of depression which followed. But Neolithic man belongs to the later part of that period of depression when the ends of some of the river gravels were again depressed below sea level and the valleys had scarcely sufficient fall for the rivers to flow freely to the sea. In the stagnant swamps and meres thus caused the Fen deposits grew, and in this time the Shippea man met his death mired in the watery peat of the then undrained fens. Human bones have not been very often found in the Fen, and when they do occur it is not always easy to say whether they really belong to the age of the peat in which they are found or may not be the remains of someone mired in the bog or drowned in one of the later filled up ditches. That they have long been buried in the peat is often obvious from the colour and condition of the bone. By the kindness of our friends Mr and Mrs Luddington my wife and I received early information of the discovery of human bones in trenching on some of their property in the Fen close to Shippea Hill near Littleport and we were able to examine the section and get some of the bones out of the peat ourselves (Fig. 6). A deposit of about 4' 6" of peat with small thin lenticular beds of shell marl here rested on lead colored alluvial clay. In the base of the peat about four inches above the Buttery Clay a human skeleton was found bunched up and crowded into a small space, less than two feet square, as if the body had settled down vertically. _b_ +-----+ / \ [Greek: ph] --------------/ \-------------- _c_ ···_d_ / \ _d´_··· _c_ / \ + -----------/ _a_ \----------- _e_ / \ _e´_ ---------+-------------------+--------- _a._ Kimmeridge Clay forming Shippea Hill, on which monastic buildings in connection with Ely Cathedral formerly stood. _b._ Patches of rusty flint gravel. _c._ Peat with bones of beaver, boar, urus, etc. _d._ Shell Marl, occurring in lenticular beds of limited extent in the upper part of the peat, sometimes in one bed as at _d_ and sometimes in several distinct beds as at _d´_.
