 All below this point can be broughl in comparison with tin- beds of 3 and

 below it the contacl with strata is plainly shown. A.s a whole it seems 

 plain that the strata of this section are finer grained than those of any 

 corresponding outcrops farther west. Cross-bedding is very beautifully 

 shown in the sandy and gravelly rocks on the knoll and connecting ridge.

there are none of special importance in determining the succession of strata 

 present. All over the slopes are scattered croppings of minor extent which 

 can not be directly correlated with definite strata of the large section-, bul 

 none is found which does not have its equivalent 



The leaf-bearing beds which have been visited l>v those in search of 



fossil plants are situated chiefly on the southern and southwestern slopes 



of the mountain and an- in minor outcrops. Possibly none of them have 

 been associated in consecutive outcrops with the darker conglomerate 

 beds. Asa rule the best-preserved leaves occur in tine, yellowish-brown 

 sandstones or clayey strata in which the nature of the constituent mineral 



particles is not always plain to the unaided eye.

of the earlier and of the most recent collections is on the south slope of the 

 southwest point of the mountain, opposite tin- Reform School. These strata, 

 at about 100 feet below the Wasalt. are water-bearing, and the Reform 

 School authorities have dug into them, making an artificial spring which 

 furnishes a water supply for the school. The rock taken out here is full
