T153] LIMESTONE OF EIPLEY GROUP. 103 



The outcrops E. of Ripley furnish, probably, the best material for 

 quicklime in that neighborhood; that which contains numerous 

 st ms of corals seems to be best. Most of the bored limestone 

 occurring there is rich in green sand. On the road from Ripley to 

 New Albany, the coralline limestone crops out in numerous 

 localities ; the same is the case on the Ripley and Molino road, and 

 also no doubt, in the country intervening between the two roads. 

 The locality near Stubbs' (IT 133) will no doubt furnish good 

 material both for quicklime and for agricultural purposes. In the 

 "Buncombes", limestone frequently crops out on the hillsides ; that 

 at Parson Montgomery's (T13fy is known to make good lime, and 

 so probably will that at the King's Place (f 1.6). On S. 29, T. 7, 

 R. 4 B., ou the Tardyville and Ellistown road, good limestone 

 appears ou the surface ; as it does in many localities in the hills S„ 

 of King's Creek. The bluff on Labatubby, S. 36, T. 8, R. 2 E., 

 affords a fine chance for au establishment on a large scale, so far 

 as the quality and quantity is concerned, and the same may be said 

 with reference to the outcrops on the edge of theFlatwoods at Mr. 

 Stephen Daggett's, ou SS. 3 and 30, TT. 9 and 10, R. 3 E.

 such as is used by him in burning lime for sale, gave the following

 One cwt. of this rock will yield somewhat over 60 lbs. of burnt 

 lime containing about 1 1 lbs. of impurities; which, however, for 

 want of intermixture with the lime, do not impart hydraulic 

 properties to the latter, since it slakes with energy. This lime 

 answers every architectural purpose except whitewashing. It is 

 due, no doubt, to the large amount of potash which the lime made 

 from this limestone contains, that effects unusually favorable were 

 observed to follow its application to soils, in the neighborhood of 

 Pontotoc. Yet this rock contains but few visible grains of green- 

 sand. — In this respect, it is greatly surpassed by the rock of an 

 outcrop 1 mile S. of Pontotoc, on the Houston road, which never- 

 theless, by careful burning, could also be made to serve for quick- 

 lime. The "horsebone limestone" near Redland, and southward to 

 the end of the formation, is generally of a similar character.
