sliillings or even pounds. We have, however, often spoken out as to the 

 money-value of fossils. They have no real money-value, and to collect, through 

 the mediiun of workmen, good fossils, there is only one way of succeeding, and 

 that is to encoiQ-age the most intelligent of them in any special locality, and to 

 recompense them Jiberally for submitting all they obtain at first-hand and intact 

 to your notice. 



Class-Lectures on Geology. — Sm, — Can yon kindly inform me of any 

 class for the acquisition of the science of Geology, as I wish to devote my 

 leisure to it. I would not have troubled you, but I find the evening classes at 

 King's College do uot comprehend this science within theii* course of study ; 

 that at the Working Man's College also it is not taught. ^Vhere else to apply 

 I know not, and as, from the popidar character of your periodical, I judge you 

 may possibly be better acquainted with such classes than most men, I have 

 ventured to trouble you. A reply on the cover of next month's Geologist 

 will much oblige, E, H., Hackney. — Class-lectures for geology and palseontology 

 were commenced during their last session at the rooms of the Geologists' Asso- 

 ciation, 5, Cavendish-square, and will be continued during the ensuiug and 

 future seasons. We regret E. H. did not think fit to entrust us in confidence 

 with his name, as we could then have commiuiicated every particular to him 

 by post. It is not our practice to answer queries on the -^Tapper of our 

 Journal; and although we did so last month in answer to E. H., we shall not 

 break through our ride in any futui'e instances ; nor shall we feel ourselves at 

 all bound to notice purely anonymous communications. We suppress the names 

 of our correspondents on all occasions when requned to do so, but tlie absence 

 of the private communication to oui'selves, as in this case, frequently causes 

 needless trouble and expence, especially when the queries reach us late in 

 the month. 



Weathered Rocks, near Keswick. — xY very interesting commimication 

 from Mr. T. Rupert Jones in Ko. 20 of The Geologist relating to the 

 " weathering" of granite-rocks, has reminded me of wliat I observed on a late 

 visit to KesAvick in the surrounding scenery. I remarked that the masses, 

 great and small, of the prevailing rocks, Silurian and igneous, strewed around 

 on the sides of the mountains and in the valleys and ravines exhibited an 

 amount of roiouUncj-off of their angles, equalling that of the boulders of primitive 

 and secondary rocks met with in the di'ilt of the eastern counties ; and as these 

 masses cannot have experienced the attrition or friction consequent on transpor- 

 tation, their bouldered-state must be the result of tceathering . 



During the same ramble I remarked to a companion how much the summits 

 of some of the mountains resemble craters in volcanic districts, except that 

 they were too small for the result of volcanic action. If I recollect rightly, I 

 particularly observed one near Buttermere, on my way to Keswick, through 

 Kewlands, as looking towards the Mere. Probably these hollows have resulted 

 sunilarly to those mentioned by Sir Hemy de la Beche in a note on the " Re- 

 port on Cornwall, Devon, and West Somerset," and their cause explained by 

 Mr. Ormerod in his table of Tors and Rock-basins.* As it is probable that 

 many of your readers have not heard of the " Bowder-Stone" in Borrowdale, 

 I will give an account of its magnitude as recorded in a hand-biU sold on the 

 spot. The dimensions are as foUows, viz., length 62 feet, perpendicular height 

 36 feet, circumference 89 feet. It contains 23,090 solid feet, and weighs 

 1971 tons 13 cwt. 



Bowder-stone, as above written, is of course a corruption of Boulder-stone, 

 or Bowlder-stone, as Webster has it in his dictionary. I send these few words 

 for the use of juvenile geologists, that they may not interpret the above de-
