222 EiiJGINEERING FOR LAND DRAINAGE. 



than other land which is improved in a similar manner, 

 which is rarely the case. The improvement of land of 

 this character is susceptible of being figured out with 

 reasonable accuracy beforehand. Two items in the 

 above schedule should receive particular attention, 

 namely, the cost and efficiency of the proposed drainage, 

 and the value of the soil for productive purposes when 

 drained. 



What will it cost to reclaim it and what will it pro- 

 duce after it is reclaimed and improved ? are the points 

 to be investigated by the engineer and purchaser. 



Conclusion. 



It has been the aim of the writer of this book to 

 place within the reach of the engineer, the thorough 

 agriculturist, and careful buyer of unimproved land 

 such information and practical details of work as will 

 enable them to engage in the work of land drainage 

 intelligently and successfully. All has not been said 

 which might be said upon this important subject. 

 Doubtless many details have been omitted which it 

 would have been well to insert. Be that as it may, the 

 book is not loaded up with useless matter nor with un- 

 tried theories, but is practical and easily understood.
