In default of more recent infoinintion, we reproduce the paragraph written l)y 

 the I\ev. E. jMaule 0>\e for the Whitby Meeting of 1SS5 : — Denudation, or in 

 other words, rain and rivers, have excavated the dales of Cleveland as well as 

 the valley of the Esk itself The Kelloway rock once in all probabihty extended 

 from Saltersgate and Simon Howe across to the Cleveland Hills, but it has now 

 ■quite disappeared in the area between these points. The Lower Oolites form the 

 top of the moorlands, but ihcy too have been greatly denuded, nud only a capping 

 is left. The deep si(les of the dales are excavated in Liassic rocks. As the dales 

 'flre not obscured by boulder clay, they remain in the state impressed upon them by 

 ■ordinary denudation. It is different with the Esk Valley ; there, as we learn from 

 the official report of Mr. C Eox-Strangways, the ancient valley has been filled with 

 boulder clay, and the modern stream has cut its way, sometimes through this glacial 

 <iebris, sometimes through the native rock, thus exposing good sections of the Lias. 

 A-Ve have found the pectcn- bed well exposed in the Murk Esk just above Grosmont 

 station. This is one of the two beds {peiteii and avicula) which are worked for 

 ironstone at Grosmont, and which belong to the A. spinatus zone of the Middle 

 Lias, but, as Mr. Fox-Strangways thinks, at a lower horizon than the main scam 

 of Cleveland. 



On tlie coast a fault has let down the rocks on the west side of Whitby Abbey 

 to a depth of some 150 feet. The Lias entirely disappears, and the sandstones of 

 the Lower Oolites are only visible for a short distance from the west pier. Then 

 to Sandsend (3 miles) the low cliffs are composed of boulder clay. At -Sandsend 

 the A. coniiiiiinis zone of the Upper Lias, which supplied formerly the alum of 

 ■commerce, again forms the lower portion of the cliff, the to]) being capped with the 

 Lower Oolites. Proceeding northward towards Kettlcness, the A. serpcnliiuis zone, 

 which contains jet, is met with, rising in the cliffs ; then the A, anniihiiu^ zone, 

 ■with numerous pyritous doggers, most of which contain the characteristic annnonitc ; 

 ■and, lastly, the A. spinatiis zone, with its beds of ironstone and splendid pecten and 

 helemnite fossils. 



BOTANY.— Tlie Botanical Section will be officially represented by its 

 T'resident, Mr. P. F. Lee, and its Hon. Sees., Mr. A. H. raw;>on (I'h:inerogamic), 

 ^Ir. M. E. Slater, F.L.S. (Cryptogamic), and Mr. Charles Crossland (Mycology).

plants known to occur in the district was published in the August and September 



numbers of the Naturalist for 1888. 



Mr. M. B. Slater, F.L.S. , writes as follows :— The fine shady glades of the 

 woods at Mulgrave will most probably be a good hunting ground for the Fungi. It 

 is also very good for the other sections of Crytogamic botany, as it abounds in Ferns, 

 Mosses, and Hepatics. The showery weather during the month of August Mdll 

 ^i^ve much assisted the growth of the autumnal species, and members studying this 

 :group Mill hcive the oj)]V)rlunity of gathering some interesting species cjf both 

 ^^osses and Llepatics. The following 'is a list of the kinds likely to be found in 

 rgood fruiting condition at this season : —
