purposes. There are a few small houses built of it near the head of Little 

 Stranger, and there may be more. It is, however, mostly very friable, and 

 the harder beds must be looked for. 



Finally, the resources of Leavenworth county may be summed up thus: 

 Abundance of coal, that will last for several generations; practically inex- 

 haustible quantities of brick shales that will pave a hundred cities, brick 

 clays for all .classes of buildings, some building stones, both limestones and 

 sandstones, mineral waters in various parts, and soils of unsurpassed fertility, 

 all of which only await his bidding to be of service in "the amelioration of 

 man's estate."' 



WYANDOTTE COUNTY. 



This county is sub-triangular in form, and two of its sides are bounded 

 by the Missouri and Kaw rivers. Though narrow from north to south, the 

 rise from each river to the central upland is rapid, and the elevation reached 

 is in places over 1,000 feet above sea level. A considerable portion of the 

 northwest forms part of the sandstone horizon previously described. 



The geology is not very different from that of Leavenworth county. The 

 bedrock belongs to the coal measures. Thirty years ago Professor Mudge 

 said that the dimension rock, which figures so conspicuously about Leaven- 

 worth, was found on the river at Quindaro. It is now impossible actually 

 to trace the continuity of stratum from one place to the other, or to say that 

 it is not continuous, owing to the covering of the lower beds of the river 

 outcrop by the debris of the railway embankment and by landslides. It 

 would take a very close and long-continued observation to determine the 

 continuity or otherwise of the limestone strata through the river front of 

 these counties. It ought to be done, but the present writer has not had the 

 time at his disposal to accomplish it. I will repeat here the section at 

 Leavenworth with which to compare the following rock sections in Wyan- 

 dotte county: 



A. 



10. Rough limestone (Pilot Knob) 10 ft. 



9. Black and lighter shale 6 ft. 



8. Dimension rock (upper) 2 ft. 



7. Shales and sandstones with some limestone ledges 250 ft. 



6. Rough limestone ledges with intercalated shales 6 to 8 ft. 



5. Yellowish green shale 3 ft. 



4. Rough limestone 14 ft. 



3. Black shale 5 ft. 



2. The dimension rock 2 ft. 



1. Slaales to the river. 



The lower part of No. 7 contains the brick shale of the soldiers' home. 

 On the Missouri front, east of Quindaro, we get this section: 



B. 



g. Rough limestone with shale partings 20 ft. 



f. Shale (brick) 12 ft. 



e. Limestone, with fossils and intercalations of shale 5 ft. 



d. Shale 5 ft. 



c. Limestone, with layers of chert 10 ft. 



b. Laminated shale (limy) 2 ft. 



a. Dimension rock (?) 3 ft. 



In one place the lower layers of (e) are consolidated into one and simulate 

 the dimension rock. Which of these, (a) or (e), did Professor Mudge identify
