Length of Navigation of the Mississippi River. 



The length of navigation of the Mississippi River itself for ordinary large 

 steamboats is about 2,161 miles, but small steamers can ascend about 650 

 miles further. The following are its principal navigable tributaries, with 



the miles open to navigation:

The other ten navigable tributaries have less than fifty miles each of naviga- 

 tion. The total miles of navigation of these fifty-five streams is about 16,500 

 miles, or about two-thirds the distance around the world. The Mississippi 

 and its tributaries may be estimated to possess 15,550 miles navigable to 

 steamboats, and 20,221 miles navigable to barges.

How to Measure Corn in Crib, Hay in Mow, Etc. 



This rule will apply to a crib of any size or kind. Two cubic feet of good, 

 sound, dry corn in the ear will make a bushel of shelled corn. To get, then, 

 the quantity of shelled corn in a crib of corn in the ear, measure the length, 

 breadth and height of the crib, inside of the rail; multiply the length by the 

 breadth and the product by the height; then divide the product by two, and 

 you have the number of bushels of shelled corn in the crib. 



To find the number of bushels of apples, potatoes, etc., in a bin, multiply 

 the length, breadth and thickness together, and this product by 8, and point 

 off one figure in the product for decimals. 



To find the amount of hay in a mow, allow 512 cubic feet for a ton, and 

 it will come out very generally correct. 



The Great Canals of the World. 



The Imperial canal of China is over 1,000 miles long. In the year of 1861 

 was completed the greatest undertaking of the kind on the European conti-
