itil lie s<ic at the head of a deeply cut valley, running norlhwartls to Milton and 

 the river Trent. There is a great deal of unmapped Permian in this district 

 which has still to be minutely explored. The Bunter extends eastward consider- 

 ably beyond the limits shown in the map, and rests directly on the Millstone 

 Grit, the boundarj- between the two formations being a natural and not a faulted 

 one. 



At the village oi Ticknall we pass over an inlier of Mountain Limestone. 

 This patch of limestone, and also the two smaller exposures of Calke and 

 Dimniinsdale, and the inliers of Breedon Hill and Breedon Cloud still further to 

 the E. , owe their present position to the intersection of two systems of foldings 

 or puckerings which have taken place at right angles to each other, and which 

 have resulted in throwing the rocks into a number of domes or ridges. The 

 tops of the these domes and ridges have been denuded down to the underlying 

 Mountain Limestone. The quarries of Ticknall are well worth a visit, as the 

 Mountain Limestone here exhibits many points of interest, which indicate a 

 shallow water deposit, such as current Ijedding, &c. At Ticknall, we are very- 

 near the southern margin of this formation, which is rapidly thinning out in the 

 direction of the old coast line of Charnwood Forest. From a little E. of 

 Ticknall to Melbourne we are again on the Millstone Grit, which gives origin to 

 the fine, grey, sandy soil that has made the latter place a centre of large market 

 gardens. 



A little E. of Melbourne the grey colour of the fields and gardens suddenly 

 changes to red, an indication that we have passed from the outcrop of the Mill- 

 stone Grit once more to the red coloured rocks of the Keuper. 



In the river escarpment at Castle Donington, the full thickness of the Lower 

 Keuper Sandstone is exhibited, from its junction with the Upper Keuper ^Larls 

 ■S. of the town, to its unconformable junction with the Carboniferous rocks near 

 the level of the river. There are many interesting sections in the neighbourhood 

 of the town. At the gas-works there was \-isible, a little time ago, a most beau- 

 tiful section, showing the Lower Keuper resting upon the denuded edges of 

 Grits and Clays of the Lower Coal Measures. This is now obscured, but indi- 

 cations are still to be found of the breccias near the point of junction. This 

 section has been described recently by Mr. Jas. Shipman, F.G.S., before the 

 Nottingham Natural History Society, and from his paper the accompanying 

 woodcut has been taken.

 edges of Lower Coal Measures. 



During the walk from Castle Donington to Melbourne a fine new will be 

 obtained of the flat topped hill of Breedon (Mountain Limestone), which is 

 liounded on its eastern side by a fault, parallel with the northward prolongation 

 of the great anticlinal fault of Charnwood Forest. The hills of the Forest may 

 be seen rising to the South.
