In town of Ecorce, section 22, is a spring veiy strongly inapregnated. 

 It occupies a basin of 100 feet diameter. This spring, with the one 

 above mentioned, probably exceeds in strength any others in the State. 

 They are favorite resorts for domestic cattle, as well as for deer and 

 pigeons. 



On section 20, town of Dearborn, several sulphur springs issue copi- 

 ously from the bank of the Rougo. Their waters also contain iron, 

 which imparts an inky color to surrounding surfaces, by combination 

 with the characteristic acid of their vegetable portions. 



A spring of considerable strength issues from the bank of the Huron 

 a mile below Flat Rock. 



On section 29, Brownstown, a spring, strongly impregnated, rises in 

 the edge of a tamarac marsh, forming a large basin. The stream is- 

 suing is suflSciently large to overspread a considerable tract. Indica- 

 tions of salt and lime were present. 



Strong sulphur springs abound in the neighborhood of the marshes 

 around Gibraltar. Their vicinity is strongly colored by a milk white 

 precipitate. 



The source of these springs is noticed under the geology of Monroe 

 coanty. 



BRINE SPRINGS. 



Springs of brackish water are found occasionally through the north- 

 em and western townships ; but their position in regard to the true 

 saline district of the State, would probably not warrant the expectation 

 of profit resulting from them in the manufacture of salt. 



Several " licks " were visited in the towns of Springwells, Redford, 

 Canton and Nankin ; but they contain, mostly, the salts of lime. 



A spring, impregnated with saline matter, rises on the bank of the 

 Rouge, in town of Redford, section 27. The discharge from it is about 

 60 gallons per hour. 



In an early stale of the country, salt was manufactured here by the 

 Indian and French settlers. A hollow gum was sunk, which has long 

 since rotted away. Furnaces were constructed of brick. An attempt 

 was made a few years ago, at considerable expense, to revive the manu- 

 facture. The result was the manufacture of a small amount, half a 

 bushel of which was sold in Detroit as table salt. Sickness occasioned
