THE ESSEX FIELD CLUB. 311 accompanied his exhibition by an account of some of his amusing travel-experiences. At the conclusion of Mr. Main's interesting show and "whan that we hadde maad our rekeninges," some of the party made their way home by omnibus direct from Highbeach, while others returned through the woods to the Camp, where Mr. Warren repeated his account of the excava- tions for the benefit of some later arrivals. Passing thence through the Forest in the direction of Loughton, the starting point was reached at about 7.30 o'clock, and an interesting ramble brought to an end. FIELD MEETING AT WOODHAM WALTER (613TH MEETING). SATURDAY, 20TH JUNE, 1926. A day of unalloyed pleasure ! So may truthfully be summed up this expedition into a hitherto unexplored district of our beautiful county, favoured as it was by exceptionally fine sunny weather. Owing to the still persisting lack of railway facilities, the outcome of the shortage of coal due to the unhappy stoppage of mining activities, a private motor char-a-banc had been hired for the occasion, and duly left the Club's headquarters, the Stratford Museum, at 10.30 o'clock, fully loaded with its complement of 2S members. Further parties travelled by motor-cars, making 38 members who assembled at the Bell Inn at Woodham Walter, which was reached at 12.15 o'clock after a delightful journey through the pleasant Essex countryside. On arrival the party was joined by a contingent of a dozen members of the Chelmsford and District Field Club under the leadership of our own member, Mr. Henry Mothersole, who, with Mr. Francis W. Thorrington, acted as conductor to the combined parties throughout the day. Before entering upon an extended walk lunch was disposed of in a field above the village, whence charming views over the surrounding country and peeps into the blue distance across the Blackwater valley were enjoyed. A ramble through the fields and along private paths (not without expostulation from a local resident) brought the party to Woodham Walter Common, where some huge nests of the large Wood Ant (Formica rufa L.) were studied from a discreet distance. The swarms of active ants, some carrying their caterpillar-prey into the nest and giving off emanations of formic acid, which could readily be scented by waving one's hand close above the nest and then smelling it, attracted considerable interest. Many plants of Lily-of-the-Valley (Convallaria majalis), apparently non-flowering, were seen growing on the Common, which was thickly covered with scrub-oak, broom and bracken. En route some magnificent spikes of Orchis maculata were noticed in damp spots, and Orchis morio was also found in small quantity. Other floral trophies included Ranun- culus sardous, Hypericum pulchrum, Linum catharticum, Trifolium procumbens, Vicia tetrasperma, V. hirsuta, Lathyrus nissolia, Tragopogon pratensis, Symphytum peregrinum, and many others.
