 The band of tuff" or breccia, directly below this limestone, may 

 be traced south almost continuously to Cope's Creek, displaced 

 here and there by cross-faults. There is frequently a consider- 

 able amount of limestone-fragments in this tufi-breccia, but only 

 occasionally are there any large masses of limestone, such as 

 those in Portions 23 and 33 (the latter of which contains small 

 forms of Favosites multitahulata. The limestone also occurs in 

 Portion 32, and in several localities west of Black Jack. One 

 of these masses has a maximum width of sixty feet, dipping 

 nearly vertically , and contains pentameroid shells. Cyatho- 

 phyllum, Heliolites, a Stromatoporoid, globular masses of Favosites 

 gothlandica and Tryplasiuu(l) which characterise the horizon.
