the east side of the ridge or beach of the former lake, (which will be 

 hereafter noticed,) aud in the same manner as we often find iron sand 

 washed iip and deposited by the waves. A little west of Palmyra, one 

 of these deposits stretches along the beach ridge for half a mile, having 

 a width of a few rods, and a thickness of eighteen inches. 



After much fruitless examination during the past season, I became 

 •onvinced that no formations of ore exist in the counties examined 

 which will compare in extent with those from which iron is manufac- 

 tured in Indiana, near the border of this State. Beds of it, indeed, oo- 

 our, some of which may be considered as of practical value. 



Although the kidney ironstone makes its appearance at several points, 

 which might have been deemed favorable to the depositing of a bog 

 ore, resulting from the mineral in those beds, none was found associated 

 with it I was led to search for bog iron in this vicinity, more partio- 

 mlarly from the circumstance that a mixture of the two forms of ore k 

 lisually made at the kidney ore furnaces, in order to facilitate smelting. 

 Some deposits of bog iron in the southern part of Branch county, in 

 fractional town of Algansee, are of suflScient extent to be valuable for 

 this purpose, should a furnace be established at the kidney ore beds of 

 that county. One of these deposits was traced over more than an 

 acre. 



Along St. Joseph River, in St. Joseph county, small beds of ore and 

 ferruginous sands were found, and also in town five north, range ten 

 west, section nine. These are mentioned, as they may be of value from 

 their vicinity to the beds of kidney iron in this part of the State. But 

 should it be ascertained that the chief benefit of a mixture of the two 

 ores results from (he carbonate of lime supplied by the former, the maW 

 ieds, which abound throughout this district, will furnish a ready and 

 cheap flux to facilitate the operations. 



The most considerable beds of bog iron ascertained during the past 

 season, were in Oakland county. The following are worthy of no- 

 tice: 



In town of Lyon, section thirty, a good lively ore is found, occupy- 

 ing in the whole several acres. 



Town of Orion, section twenty-four, deposits were traced at intervals 

 over an extent of twenty acres. The richest and most abundant form 

 of the ore was in the state of a yellow ochre.
