along the road, but here a new h\ siein sets in, consisting of two or 

 possibly three strata, although in the drawing they are represented as 

 being continuous. Each stratum is composed of a number of differ- 

 ent layers, no one of which is sufficiently thick to produce good 

 dimension stone. There can be little doubt that this system 

 continues northward to Ottawa, where it is exposed in the bed of the 

 Osage river. Tlie reasons for this view are that it can be traced 

 almost continuously from Welda to Princeton, and that the road bed 

 remains on top of the series from Princeton to Ottawa, at which place 

 a limestone is seen in the bottom of the river. At several points 

 between Welda and Richmond where the road crosses deep ravines 

 the road bed passes below the limestone. In such cases the latter 

 may be seen along the bluffs near by, the two different strata being 

 separated by lo or 15 feet of light colored shale. P^arther north the 

 sliale becomes black, anil in some places it looks almost like coal. 

 The north bank of the little stream just south of Princeton exhibits 

 tlic two limestone strata with the characteristic black shale between. 



To the north of Princeton no limestone can be seen near the road 

 until Ottawa is reached, where it appears in the bed of the Osage 

 river, as above stated. As the road bed is above the rock at Prince- 

 ton ami also at Ottawa, it leaves little room for doubt that the 

 limestone system is continuous between the two points. 



To the west of the line of the road at different places a system of 

 hills can be observed with limestone near their summit. This is ])rob- 

 ablv the same as the upper limestone on the north bank of the river 

 at Ottawa, but ])Ossibly it corresjionds to that on the hill tojjs in the 

 vicinit) of Lawrence. I'urther work should be done before exact 

 correlations can be made. 



Again we may with a considerable degree of certainty decide that 

 the limestone system, just described, anil which will ])ro\ision'ally be 

 called the Garnett limestone, is identical with number 6 of the 

 Neosho river section which is exposed so extensively in the vicinity 

 of Burlington, and which has already been named the Burlington 

 limestone. The evidence upon which this conclusion is based is 

 quite strong. In each case the system in question has a vertical 

 distance above the Carlyle limestone of 140 or 150 feet. The system 

 is composed of two or more strata separated by only a few feet of 

 shale. The general character of the rock in each case is very simi- 

 lar, being a light buff" limestone well stratified in thin layers, none of 

 which are more than twelve or fourteen inches thick, while some are 

 much thinner. The southeastern limit at the two points, as repre- 

 sented in the different drawings, are in about the proper positions to 

 correspond with the southeastern outcropping of one rock system
