as to whether the latter limestone is an equivalent of the beds that are 

 worked at Forcett. The opinion seemed rather to lean to the view that 

 the Merrybent limestone is a lower member of the Yoredale series, than 

 the one represented by the Main limestone.— In the neighbourhood of 

 High Force the geologists had many opportunities of becoming acquainted 

 with the characteristic features of the Whin Sill ; but as the geological 

 connections of this bed have been already pointed out, it is not necessary 

 to enlarge upon this point. There are, however, many interesting minor 

 features to be observed in the district — such as small veins and dykes, 

 several of which yield mineral specimens of considerable value and interest. 



There was nothing specially noticeable from a geological point of view 

 in connection with the Glaisdale meeting. The exposure of the Whin 

 Dyke in nearly its eastern limit was observed, and several good sections 

 of the ironstone strata were seen. In this part of Cleveland the Main 

 seam is broken up into two layers, separated by a considerable thickness 

 of shale, but the measures are worked at some considerable distance from 

 the surface, and do not contain a very high percentage of iron. In the 

 visit to Greta Dale the most striking features of the Yoredale series of 

 the carboniferous system were presented to view. These have been so 

 well laid down by Phillips that scarcely anything remains to be said as to 

 general classification ; but it is evident that even over limited areas the 

 character of the limestone is subject to considerable variations, which 

 modify its value in a commercial sense. — The last meeting of the season 

 was held at Saltburn, in October, and was chiefly devoted to the geology 

 of the ironstone series. The measures succeeding the Main seam of iron- 

 stone were traced out from Hob Hill down to Saltburn. It is proposed 

 to wind up the field days each year by holding a meeting at Saltburn. — 



Rainfall for fanuarg. 



HuDDERSFiELD.— January has proved a very wild, wet month, 4*89 in. 

 of rain having been collected in 25 days, against an eleven years' average 

 of 3*llin. in 18 days. The heaviest day's fall was on the 3rd, when 1*76 

 inches were registered, having fallen in the form of soft heavy snow. 

 1*08 in. were also measured on the 29th, — J. W. Robson, Dalton, 

 February 19th, 1877. 



Wakefield — The number of rainy days has been 23, rain having 

 fallen to the depth of 3- 64 in. The heaviest day's fall occurred on the 

 3rd, when the gauge "yielded 1-06 in. — Fredk. Hill, Kirkgate, 19th Feb. 



Barnsley (350 ft. above sea). — Total fall, 3*82 in. ; heaviest day's fall 

 jTan. 3rd, 1*29 ; 24 wet days. — Stainborough Hall or Wentworth Castle, 

 three miles W by S (600 feet) : Total fall 4-72 in. ; heaviest day Jan. 30, 

 •78 in ; 16 wet days. — Corporation Works, Ingbirchworth, 10 miles W 

 (153 feet) : Total fall 5-62 in. ; heaviest day Jan. 29th, 1*36 in. : 26 wet
