result of the work has been to demonstrate that the two beds are 

 altogether distinct, the Agoniatites limestone passing downward 

 and, in the neighborhood of Flint creek in Ontario co. becoming 

 complicated with the upper layers of the Corniferous limestone, 

 while the Stafford limestone, which appears not farther east than 

 Ontario co. and continues westward to Lake Erie, occupies a 

 higher position in the strata. The faunas of the two strata are 

 remarkably dissimilar. 



Clinton colonies in Orleans and Niagara co. As already observed 

 the colonies contained in the lenticular limestones of the Clinton 

 beds through Orleans and Niagara co.. have been studied. Here 

 also quite extensive collections were made, particularly from the 

 Clinton shales in the vicinity of Oasport and in the Niagara 

 shales near Middleport. 



Newburgh mastodon. About the middle of August notice was 

 received of the discovery of a mastodon on the farm of F. W. 

 Schaeffer, three miles west of Newburgh. The spot was visited 

 at once and an option obtained from the owner on behalf of the 

 state museum which would secure first consideration at the sale 

 of the skeleton. At the present writing the specimen appears to 

 be fairly complete in excellent preservation and negotiations are 

 now under way to secure it in case it proves a desirable acquisi- 

 tion. 



Graptolites in Colonic The writer may also report the interest- 

 ing discovery of graptolites in remarkably fine preservation in the 

 Hudson river shales at the Albany rural cemetery, not far from 

 the grave of Prof. James Hall. With the consent of the superin- 

 tendent of the cemetery, a very considerable amount of this ex- 

 ceptionally fine material has been secured. 



Graptolites in Columbia, Albany and Rensselaer co. Dr Ruede- 

 mann, assistant in paleontology, has carried on field investiga- 

 tions bearing on the distribution of the graptolites, first at Mt 

 Moreno, south of the city of Hudson, where with Mr Sheehy very 

 considerable collections were made, and subsequently at various 

 localities between Albany and Schenectady and in the vicinity of 

 Troy.
