of three square rods. Should the deposit cover but half an acre, with 

 the depth of a foot, (a low estimate,) the amount of lime it is capable 

 of furnishing would be 21,333 bushels. Five hundred bushels of the 

 lime cost in the d'gging r.nd manufacture 57 days labor. Reckoning 

 these as so many dollars, and the lime at two shillings per bushel, (av- 

 erage price,) there will appear a profit of more than one half the price 

 brought by the article. 



On the farm of Caleb Herrington, Esq., sections 5 and 8, a very ex- 

 tensive deposit was exposed in digging a drain to remove the water 

 from a tamarac swamp. At several places a pole was thrust into the 

 bed, without passing through, to the depth of six feet. From the indi- 

 cations apparent, I am led to believe that the entire area of the swamp 

 (30 acres) is underlayed by the marl. It is compact, heavy and plastic. 

 This marl is well adapted to the manufacture of lime, but has not yet , 

 been applied to that purpose. 



On land of Sylvanus Taft, section 4, is a bed of an acre or more in 

 extent, with an average thickness of two feet. It is compact and of 

 good quality. No lime has been manufactured, but much of it used in 

 its natural state, by the neighbors, for plastering and whitewashing, is 

 said to have fully answered the purposes of kiln-burnt lime. 



Numerous other indications of marl occur through the township. A 

 bed is said to exist on section 27 ; also, on farms of Mr. Holmes, and 

 others, probably to a small extent. 



A small bed was found on land of Wm. Yerkus, section 2. 



Upon the surface of a knoll at Waterford, a considerable quantity of 

 a dry pulverized marl was observed. 



On the farm of Pitz Taft, on the Base line, within the boundary of 

 Oakland county, is a deposit which may be noticed in this connection. 

 It covers two acres, with an average depth of six feet. It is a tufaceous 

 shell marl, in coarse particles, with a stratum of tufa underlying, and 

 occurs under circumstances similar to those of the deposit on section 

 22, first noticed. 



Ten square rods have been excavated, out of which were manu- 

 factured 3,000 bushels of lime, of good quality. It sells at three shil- 

 lings per bushel. 



Assuming the above proportion, the quantity of marl may be estima-
