THE IREIGATION AGE. 



(Continued from page 217.) 



I would not advise a tight plank roof. 



The floor should be made smooth so that potatoes will 

 not be injured in shoveling them onto the sorter. 



The bruising of potatoes is a serious thing. Bruised 

 potatoes will sometimes develop dry rot. 



Use a "Thompson" sorter for sorting potatoes. 



We find that a whole potato planted has a tendency to 

 set on a greater setting. 



You cannot get a big bunch of potatoes without a clover 

 and alfalfa rotation. 



I do not believe you can continuously grow potatoes with 

 continuous manuring. 



We believe in a top dressing for potatoes in Colorado. 

 We top dress one year before planting potatoes. 



My experience is that poor drainage causes scabby po- 

 tatoes after irrigation. 



You won't get scabby potatoes planted from scabby seed 

 planted in ground the previous year planted to alfalfa or 

 clover. 



You can plant your own seed from year to year. I think 

 you can grow the best of seed here. 



A good place to get seed is from that part of the field 

 producing the best growth of potatoes. 



I never saw a volunteer potato rot. It will not rot. 

 ' Do not cut seed pieces too small. It is a dangerous 

 thing. Cut potatoes right to the center. 



If potato is of reasonable size, the great strength comes 

 from the terminal bud. 



It is not a good thing to recommend the planting of small 

 potatoes. They will eventually run out. 



CORN PRODUCTION IN ARGENTINA. 



A cablegram, dated March 25, 1912, from the Inter- 

 national Institute of Agriculture, Rome, Italy, has been re- 

 ceived by the United States Department of Agriculture, giv- 

 ing the following information : 



"The estimated production of corn in Argentina this 

 season (1911-12), is 147,927,000 hundred-weight (295,854,000 

 bushels)." 



"INGECO" INTERNAL 



COMBUSTION ENGINES 



Operate your irrigation pump with an "INGECO" 

 Engine and be assured of the maximum amount of water with the 

 minimum expense. 



"INGECO" Engines embody every essential feature of high grade 

 engine d_esign and construction ; mechanically operated vertical valves 

 located in removable cages and stems are without threads or nuts to 

 work off, have no soft gaskets under explosive pressure; governor acts 

 direct on fuel valve and is of the inertia centrifugal type located in 

 fly wheel, chain oiling main bearings and automatic oiling of crank 

 permitting continuous service; magneto built on to every "INGECO" 

 Standard Horizontal Engine. 



"INGECO" Engines are easily and quickly installed, carefully 

 balanced, no expensive foundations required, every part manufactured 

 from jigs and interchangeable, constant attention unnecessary. 



Branch sales offices in all principal cities, carrying complete stocks of 

 engines and spare parts and are in position to give engineering advice 

 and furnish complete pumping plants.

READY NOW: THE PRIMER OF HYDRAULICS. 



By Frederick A. Smith, C. E., Hydraulic Engineer. 



This new book is a splendid volume of over 200 pages 

 of absolutely new matter pertaining to the subject of 

 Hydraulics and its allied branches. All the subjects 

 treated of are handled in a simple and practical way to 

 make them of use to the men -who have been unable to 

 obtain a college education, but who are successlul practi- 

 cal men in fields where they require a knowledge of the 

 principles of Hydraulics and instructions how to solve 

 their problems in a simple and satisfactory way. This 

 book is indispensable for anyone engaged in works re- 

 lating to Hydraulics, Irrigation or Drainage; it is primarily 

 designed for the practical man in the field, but will be 

 equally welcome to the trained Hydraulic Municipal and 

 Railroad Engineer especially, on account of the many 

 valuable tables compiled by the author, which will save a 

 tremendous amount of time in computations.
