SALAMONIE RIVER. 



Salamonie River enters the Wabash from the southeast a few miles 

 above the city of Wabash. It has a length of about 75 miles. Its source is 

 on the northern slope of the elevated limestone district of eastern Indiana, 

 at an altitude of about 1,000 feet above tide. Throughout the greater part 

 of its course the river follows a plain on the south border of the Salamonie 

 moraine. Its descent is measured by the descent of the plain, except in 

 the lower 40 miles, where it has deepened its channel to enter the old lake 

 outlet. Sufficient time has not elapsed since the river began flowing for it 

 to form a regular gradient. It can scarcely be said to have developed a 

 valley except in the lower 40 miles, the bed of the stream in its upper 

 course being seldom more than 20 to 25 feet below the bordering plaiA. 

 The descent from Portland to Montpelier is less than 3 feet per mile, but 

 in the 40 miles from Montpelier to the mouth the average descent is about 

 4 feet per mile.
