Other localities in the district where beds of limestone occur 

 might be cited, as for instance, between Limekilns and Sunny 

 Corner, but enough has been said to prove that there is a great 

 variety of stone, suited for building and ornamental purposes, 

 within a radius of twenty miles from Bathurst. It would, in fact, 

 be difficult to name any locality where so complete a series of 

 limestones and marbles, coarse grained and fine grained, fossili- 

 ferous and unfossiliferous, of all colours — white, black, red, blue, 

 grey, and variegated, could be obtained. 



A polished slab and several small specimens, Nos. 1 to 5, from 

 Fernbrook are shown, also samples of the other beds at Limekilns 

 Nos. 6 to 10 and 14. For comparison, a specimen of ornamental 

 stone from Kaloola, near Orange is added. This limestone carries 

 fossil corals. 



Stratigraphy of the District. 



In a paper contributed to the Geological Society of London, 

 and recently published in the Quarterly Journal,* I have sketched 

 the geology of the Bathurst District, as I understand it. In 

 order, however, to make the mode of occurrence of the Limekilns 

 rocks clear, it will be necessary to traverse part of the ground 

 alluded to in the paper. 



Let us set out from Bathurst, height about 2,200 feet above 

 sea level, on a journey to Limekilns, and note the geological 

 features of the country. We at first travel over low hills of 

 granite, capped with drift near the village of Kelso, descending 

 again to the Wimburndale Creek. This creek or rivulet follows 

 roughly the junction of the granite and slate for some distance, 

 crossing and recrossing the boundary several times. On the 

 Limekilns road, however, one has to travel for about a mile and 

 a half beyond the creek before reaching the junction. Just beyond 

 the creek the ground rises, and some fifty feet above its present 

 level, a thick bed of coarse drift occurs, marking the former level
