146 Peacock : Lincolnshire Naturalists at Revesby. 



Below the first-mentioned exposure of Kim me ridge Clay we 

 come to ' Enderby Fen,' and find ourselves on the silts, clays, 

 and peat of the old fen-land. 



These ' old river gravels ' undoubtedly form part of that 

 great drainage system of which the Trent was the chief feeder, 

 but it is not safe to describe them as actually or solely deposited 

 by that river, for no doubt other rivers drained the land between 

 the Oolite cliff and the wolds on the north, and formed feeders 

 to the main stream when it flowed through the 'Lincoln Gap' 

 into the sea ; and by this means not only might older beds of 

 gravel, deposited long before by the Trent at earlier periods and 

 at higher levels, be washed down and re-deposited in this district, 

 but fresh material from the different localities drained by the 

 side streams w T ould inevitably be brought down by these 

 streams, and mingled with the more recent deposits. Certainly 

 only a very careful examination of the remains forming these 

 Revesby gravel beds could entitle anyone to speak with authority 

 as to their origin. The following are some of the problems 

 which would require to be worked out in connection with the 

 subject. Are there any rock remains, oolitic or cretaceous, in 

 these gravel beds which must have been brought down by side- 

 streams from the area to the north or north-west? Are there 

 any flints, worked or unworked, any ice-borne erratics, or other 

 foreign bodies, in them ? Or are all the pebbles only the usual 

 quartzites and other remains of the Trent gravel beds? 



The area in question is easily accessible to those dwelling on 

 the east side of the county, and it would well repay any geologist 

 to make a thorough examination of the contents of these 

 Revesby beds. He would not only find plenty of material to 

 work on, but a careful and thorough search would certainly lead 

 to very interesting, and might possibly lead to very important, 

 results. 



On the botany, Miss S. C. Stow and Mr. J. S. Sneath 

 reported fully. About two hundred species were noted ; and 

 Sir Henry Hawley reported Orchis pyramidalis and OpJirys 

 apifera from Tumby Wood. The best Revesby records were : — 

 Some specimens of Lychnis dwica, a pale lavender pink ; Ahthyllis 

 vulnerarza, road-side, Moorby ; Myriophyllum spicattim, Satii- 

 cula and JEgopodium ; Veronica chamoedrys, with upper leaves 

 aborted into the multilarval galls by the pink grubs of Cecidoniyia 

 veronicce. ; Calaniintha ciinopodiuni and Lamium amplexicauie ; 

 Listei'a ovata very fine in Revesby Wood, and Tanuis most 

 abundant.
