appears to have been paved with flints, and then puddk^l with 

 clay in order to retain the water. After leaving these interesting 

 ruins of what must have been a very fine specimen of the old 

 English manor-house, a walk across the fields brought the party 

 to another and yet earlier fortification, a circular camp near 

 Bush Wood, probably British. Mr. Evans stated that it was one 

 of a series of three, the others being situated respectively at 

 Hawridge and Cholesbury. From a field close to one of these he 

 had obtained a bronze sword, and there could be no question as 

 to their very early date. 



The route then lay through Bovingdon back to Boxmoor 

 Station. 



Field Meeting, 12th May, 1881. 

 BROXBOURNE AND BRICKENDON. 



Leaving Broxbourne Station, the main road from London to 

 Hoddesdon was taken for a short distance, and then a lane to the 

 west brought the party into the fields, the path from which led 

 through a short avenue of beech trees to Baas Hill, from which 

 a fine view of Bi'oxbournebury House and Park was obtained, and 

 proceeding down the hill two old cottages, part of the old manor- 

 house of Baas, were visited. 



After collecting microscopic objects in a pond behind these 

 cottages, the party proceeded towards Broxbournebury, and at the 

 farm-entrance the ferns Asplenium Adiantum-nigrmn, Scolopendriimi 

 viilgare, and Polypodium calcareum were seen. Their spores had 

 probably been brought by the wind from the fernery at the Bury, 

 finding here a favourable situation in which to germinate. 



Passing into Pembridge Lane and through a wood to the high- 

 road to Brickendon, Brickendon Grange was soon reached, and here 

 the members were welcomed by Mr. and Mrs. H. Domain Saunders, 

 who kindly provided tea and other refreshments on the lawn. 



On the way from Brickendon Grange a pond on the Green was 

 visited, and from it were obtained many species of Entomostraca, 

 Hydra vulgaris, Myriophyllum, etc. The route then taken was 

 through the "Lights Wood" and down Brickendonbury avenue 

 to Hertford. 



The following plants and trees were observed in flower in the 

 course of the walk : — 



Ranunmlus hederaceus. Potent ilia reptans. 



R. reptans. Fi/rufi mains, v. acerba, 



Jt. scleratus. Ajuga reptans. 



Cardamine sylvatica, Myosotis versicolor . 



Viola odornta. Frimula veris. 



Lychnis dioica. Qitercus pediinculata. 



Vicia sepium. Orchis mascula. 



Lathyrus tuberosiis. 0. Morio. 



The meeting was under the direction of Mr. R. T. Andrews 

 from whose account this report has been compiled.
