Overview

Excerpt from The Scientific Proceedings of the Royal Dublin Society, Vol. 4: New Series This last fall is believed to have not occupied more than one fourth of a minute in its descent, although several large buildings appear to have been carried along on the surface of the debris for some distance before they fell. The material of the fall consisted Of broken, Splintery Shales, humus, and vegetation, which rested upon the upturned edges of a zone of much contorted and shat tered Shales. After settling down, the surface of the debris -pre sented the following appearance -it was about 600 yards long, Of which the lower half dipped at an angle of about and the upper at from 25 up to the vertical. Owing to the immense quantity of water which had been absorbed into the mass before it began to slide, the whole was in a semi-fluid condition, which was testified, not only by the low angle of repose, but also by the fact that those who ventured upon it sunk up to the knees. One of the principal objections urged by Mr. Theobald to my view of the origin of the barrier closing Naini Tal was, that those Slips possessed of most mobility, from the greater fluidity of their composition, are in the precise ratio of such fluidity, least capable of bearing upon their surface craggy masses of rock, such as I should term erratics. This almost ex cathedra statement assumes, what is by no means necessary, that the blocks Should be carried on the surface and it breaks down altogether when compared with the actual fact, that this Naini Tal slip; by no means an extensive one, as com pared with many others known to have occurred in the Himalayas, did carry down blocks 9 or 10 feet in diameter in the mass of detritus not on the surface. Heavy rainfall and streams acting on such an accumulation would, undoubtedly, produce an appear ance, by the removal of the finer portions, very closely resembling that presented by ordinary moraines, and such an accumulation as that which forms the retaining barrier of Naini Tal.
