 It may he remarked, in regard to No. 5, that the percentage of silica 

 alumina, and iron is exceptionally small. The bluer courses show a con- 

 siderable increase, as is seen in analysis No. 7.

 No. 8 shows the composition of Stitt and Price's best lime. The speci- 

 men analyzed was selected from the kiln with reference to quality — and 

 the results both of this analysis and of No. 6, will scarcely be sustained 

 by any large quantity. Still, if lime of exceptionally good quality was 

 desired, it could be secured from these known horizons of the quarry.

Nos. 9, 10, 11, and 12, all represent the Delaware beds in their different 



phases. The first three analyses were made from the shales that are 



shown in the State quarry section. The varying proportions of silioious 



matter will be noticed. Samples could easily be selected that would yield 



much larger percentages than these.
