The Quarterly journal of the Geological Society of London . tbe tarn is only about 20 feetabove the tarn-level, it simply re-quires a thickness of about 50 feetof moraine-matter to form the infant Mite runs below the cirquefor a long distance in a narrowcliff-bound gorge with an alluvialfloor. It may be remarked that thedrift-filled gorge in the cirque iscontinuous with a depression withina depression, extending between thispoint and the tarn, probably indi-cating the existence of the gorgesome way above the point of itsexposure in the cirque. The case of Burnmoor Tarn is of interest, not only as throwinglight upon the formation of some mountain-tarns, but also asindicating one of the many causes for the complexity of the LakeDistrict drainage, which I hope to discuss elsewhere on a futureoccasion. Suffice it to say here that the upper two miles of whatwas once Miterdale is now made a portion of the Eskdale drainage-area, and the Mite is thus robbed of the distinction which it oncepossessed of rising on the summit-slopes of [For Explanation, see p. 47.] VI. Tarns in the Scaweell Group. Situated upon the northern slopes of the Scawfell group of hillsare three well-known lakelets, Sty Head, Sprinkling, and AngleTarns. None of these, so far as I am aware, have been first, Sty Head Tarn, near the top of the Pass of that name, is1430 feet above sea-level. It now receives the water from SprinklingTarn, which, as will be presently maintained, once drained in adifferent direction ; but this stream is probably quite insignificant intime of flood when compared with the short stream descending from 44 J.
