HERTFORDSniKE NATURAL iriSTORY SOCIETY. XXVU 



Brocks-bourne to Eose Hill, where they were most kindly received 

 and entertained by IMr. and Mrs. Campbell. Mr. Andrews theu 

 read a paper on the jS^atural History and Archaeology of the district 

 visited, and !Mr. "Whitley gave an account of the evidence ho had 

 collected which proves that Hoddesdon and its neighbourhood luid 

 once been a district of great note, the llomans having had here 

 beacons, fortresses, tumuli, barrows, and other earthworks. 



After tendering their thanks to Mr. Campbell the members left 

 for tlie Rye House station.

PiELB Meeting, 17th June, 1882. 



EICKMANSWOETH. 



The Harefield chalk-pits, close to the river Colne below Eick- 

 mansworth, expose as fine sections of the Upper Chalk as any to 

 be met with on the northern side of the London Basin, and no- 

 where can better examples of "pipes" in the Chalk be seen than 

 in one of these pits, while the absence of any vestige of a pipe in 

 the other affords an instructive lesson in physical geology. But 

 scant notice, however, of these sections has hitherto been taken. 



To examine these pits, and also sections of the Tertiary beds at 

 "Woodcock Hill, under the guidance of Mr. "William "Whitaker of 

 the Geological Survey of England, and Mr. John Hopkinson, the 

 members of the Society assembled at three o'clock at Eickmans- 

 worth station, where they were met by members of the Geologists' 

 Association of London, the united party numbering between forty 

 and fifty. 



Proceeding down the valley of the Colne, a slight detour was 

 made to inspect a small disused chalk-pit on Stocker's Farm, of 

 but little interest, and then a short walk along the towing-path 



* Or Lathyrus macrorrhizus. In tlie report of a former field meeting 

 ('Transactions,' Vol. I, p. Ixi, April, 1882) this plant is mentioned iu error as 

 Lathyrus tuberosus, a much rarer species not found in Hertfordshire.
