remains of charred stick at the bottom of some of the pits, as if chalk 

 had been burnt with wood. He gave the facts and traditions simply for 

 what they were worth, but they appeared to him to be of interest. 



The river Yeo had its source under the bridge upon which they were 

 standing, whilst the principal source of the Frome was at St. John's Well, 

 Evershot, but water ran within a few yards of the bridge to the Frome. 

 With reference to the question as to what the name of the place was, he 

 said that the names given by Hutchins were Ailwell and Caldwell, the 

 derivation of which he did not know. Holywell was probably only a 

 corruption of Oily- well, there being a tradition of a pond there being at 

 times coated with an oily substance. 



The party then proceeded to Spring Pond, which is prettily situated in 

 a wooded depression, and was fed originally by seven springs, which were 

 reduced to three by the making of the railway tunnel. The pond and 

 plantations were probably at one time a portion of the grounds of Wool- 

 combe House, now almost entirely pulled down. 



The HON. SECRETARY read the following valuable geological notes 

 communicated by Mr. A. J. Jukes-Browne, F.G.S. : The country south 

 of Mel bury Park consists mainly of upper greensand resting on the Oxford 

 clay and capped by long promontories of chalk. It is possible that a 

 diminutive representative of the gault occurs at the base of the green- 

 sand ; but in the absence of any clear section at the junction it is very 

 difficult to say whether gault is present or absent. If present it would 

 be a dark-grey micaceous clay with patches and seams of dark-green 

 glauconite grains. The discovery of such a bed in the neighbourhood 

 would be interesting. It certainly occurs near Minterne. The thickness 

 of the upper greensand is probably from 60 to 70 feet. That of the lower 

 chalk is from 80 to 100 feet, and the middle chalk will be found on the 

 higher parts of the hills. The junction of the greensand and chalk can 

 be seen very clearly in a quarry by Pvock-lane, north-east of Evershot, the 

 beds here shown being :
