122 TILE DRAINAGE. 



and economically, at the times when other farm work is least 

 pressing. 



As promised in the introduction,! have not given here any 

 of what I may call the ancient history of drainage, curious 

 and interesting as is the evolution of any science or art, but 

 of little use now to the average farmer, who wants most to 

 know the best present methods, implements, and materials, 

 and the reasons why they are best. 1 have also avoided the 

 discussion of curious but really useless side issues and ques- 

 tions. But 1 have tried hard to touch all points that are of 

 real importance to those who wish to tile-drain portions of 

 their farms, and do it economically and well.
