^{page 284 note 1} The extinct river system, first observed by Major Gordon Fowler, F.S.A., and already mapped by him over part of the Fens (see P.C.A.S. xxxiii, 108–28, and xxxiv, 17–33 ; also Geogr. J. lxxix, 210, 351, and lxxxiii, 30), is visible on the modern surface and is known to have been partly active in the Romano-British period. Such borings as have been made (e.g. Antiq. Journ. xiii, pl. XLVII) indicate that these rivers have flowed in substantially the same courses for a long way back in the post-glacial period.

^{page 289 note 1} The clay is very soft, while still damp, and there would be little chance of missing a scatter of objects in it.

^{page 292 note 1} A few in fact were so decayed that they have not survived removal from the ground.

^{page 294 note 1} Owing to the difficult conditions three or four sherds were recovered without exact provenance, two pieces, for example, from a sump. On the lower slopes of the sand-ridge the surface was waterlogged, and the sand had to be held by throwing down heavy wooden horses.

^{page 304 note 1} No. 36 is interpreted as a flake prepared for the production of a microlith by the removal of the butt-end of the primary flake, by an oblique blow, the butt-end itself becoming the so-called micro-burin. In the case of nos. 37 and 38 an effort has been made to carry this out, but has ended in failure.

^{page 305 note 1} This also occurs with an oblique edge in the ‘narrow blade’ microlithic industry of the Pennines. See J. G. D. Clark, The Mesolithic Age in Britain, fig. 9, no. 31. Also at West Keal, Lincolnshire, ibid., fig. 17, no. 18.

^{page 318 note 1} This clay was deposited under water, and at the time of its deposition wide areas of the fenland must have been covered by lagoons.
