FARM ARITHMETIC PROBLEMS 99 



7. Measure the distance across the school ground 

 the long way and estimate the number of tile it 

 would take to lay one string of tiling across it. How 

 much would it cost, reckoning the tile at $20 per 

 1000 and the laying at 25 cents per rod? 



8. The very wettest of land can be thoroughly 

 drained (if a proper outlet can be had) by laying 

 lines of tiling three rods apart. To drain a field 20 

 rods wide and 80 rods long in this way, running the 

 tile the long way of the field, how much tile will 

 be required, and what would it cost ? Draw diagram. 



9. The gain in yield from tiling would be at least 

 10 bushels of corn per acre, or its equivalent in other 

 crops. If the tiling lasted for 30 years, what would 

 be the total gain ? What would be the net gain ? 



Handy Farm Measures 



1. A bushel of small grain or shelled corn is 1^ 

 cubic feet. To find the capacity of a bin, multiply tho 

 length, breadth, and depth, together (in feet) and 

 take 4-5 of it. 



2. A bushel of ear corn is 2y 2 cubic feet. To find 

 the capacity of a crib in bushels, multiply the length, 

 breadth, and depth, together (in feet), and take 

 & of it. 



3. A bushel of apples or potatoes is 1 1-3 cubic 

 feet. To find the bushels, take % of the cubic feet.
