TOPICS FOR INVESTIGATION 



1. Is there any ground on your home farm too wet 

 or marshy for cropping successfully? If so, measure care- 

 fully the amount of land in such areas. Do any patches 

 break the regularity of cultivated fields? How much land 

 is practically wasted as far as any return in crops is con- 

 cerned ? 



2. What is the value of your farm per acre? What is 

 its rental value per acre ? W T hat is the value of all the land 

 lost by being too wet to cultivate? What is its rental 

 value? Have you any land under cultivation that is too 

 wet at times to produce good crops? What do you esti- 

 mate is the loss? 



3. Draw a diagram of any pieces of marsh land on your 

 home farm, showing the outlet for drainage and the distance 

 the drain would have to run in each case. Are there any 

 places where a shallow run would serve? Have you any 

 low ground troubled with rain floods from higher land? 

 If so, could a shallow ditch be made to serve as an eaves- 

 trough to save the flooding? 



4. Taking the cost of tile drainage as shown in the 

 table, figure what it would cost to tile out wet places on 

 your farm, using four-inch tile for parallels laid four rods 

 apart. The parallels are to connect across the lower end 

 with a six-inch line, and this is to empty into the nearest 

 available ditch or stream. Would it pay to put in tile on 

 your home farm? 



5. By digging down in several different places on your
