Interesting to Advertisers. 



It may interest advertisers to know that The Irrigation Age is the 

 only publication in the world having an actual paid in advance 

 circulation among individual irrigators and large irrigation corpo- 

 rations. It is read regularly by all interested in this subject and DAS 

 readers in all parts of the world. The Irrigation Age Is 28 years 

 old and is the pioneer publication of its class in the world. 



We are presenting in this issue a 

 Lessons number of half-tone engravings illus- 



From Deep trating the experiments being car- 

 Tilling riecl on by the Spaulding Tilling 

 Experiments. Machine Company of Cleveland, 



Ohio. The method, as explained in 

 the article, shows results in the wonderful develop- 

 ment of plant roots as a result of stirring the soil 

 to a depth greater than that ordinarily practiced by 

 the users of the old time plow. If one were to ask 

 the average depth of corn roots, the reply would 

 likely be nine to twelve inches. The description 

 and illustrations of this experiment carried on at 

 Cleveland shows a corn root, where the soil was 

 stirred to the greater depth, of from four to ten 

 feet, demonstrating clearly that corn roots will 

 penetrate wherever possible in their search for food. 

 We intend to publish information concerning 

 other experiments carried on by the company in 

 future issues of THE IRRIGATION AGE. We have in 

 contemplation a series of articles along this line, 

 believing that this sort of matter will be of great 

 benefit to the ranchmen and farmers throughout the 

 West who are readers of this publication. If deep 

 tilling will double or quadruple the crop of corn in 

 the middle states, there is no reason why similar 



results may not be obtained through this process 

 in raising smaller grains throughout the arid and 

 semi-arid regions of the W T est. 



It is possible that this method of tilling by the 

 methods of the Cleveland concern will revolutionize 

 our system of agriculture in the semi-arid regions 

 of the country, as it seems to fill the need of a sub- 

 surface packer and plow combined. 



Wonderful 

 Market 

 Developing 

 in Australia. 



Word comes from Australia that 

 wonderful development is taking 

 place there in the irrigation field. 

 There have recently been shipped 

 from Chicago machinery exceeding 

 in value a half million dollars, all of 

 which has gone into the irrigation territory of 

 Australia. 



The editor of THE IRRIGATION AGE, by a letter 

 received from one of the officials there dated Febru- 

 ary 25, is informed that four large new machines 

 were recently started to work there, all of which 

 were made in the city of Chicago. These machines 

 range in prices from $2,500 to $10,000. It will be 

 seen from this that American manufacturers are 

 opening up a fine market for high grade earth 

 handling machines and implements in that country.
