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 has 

 readers in all parts of the world. The Irrigation Age is 22 yean 

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



The most southerly of California counties 

 The Climates ^ s San Diego, and none is more interest- 

 in One ing. It extends from the Pacific Ocean 

 County. to Arizona and is bordered on the south 

 by Mexico. 



The surface rises gradually from the sea to the 

 San Jacinto mountains range, which runs across the 

 county about forty miles from the shore. Of this 

 slope there is a zone along the ocean that is frostless 

 and nearly stormless, one of the most perfect climatic 

 conditions the year around in North America. 



Back of this, a little higher, there is a two-season 

 zone, a long, dry summer and short, cool, somewnat 

 rainy winter, with some frost. Then comes a third zone, 

 still more elevated, with more marked seasons, colder 

 in winter, with an increased rainfall. 



Near the mountains there is a real four-season 

 climate spring, summer, fall and winter. In a short 

 ride one can go from the land of everlasting May and 

 everblooming flowers to a region where sleighbells jin- 

 gle and overcoats are needed. 



These San Jacinto mountains are really a continua- 

 tion of the Sierra Nevada range. They reach an alti- 

 tude in some places in San Diego county of 6,000 feet. 

 The rainfall in the four-season zone is 35 to 40 inches, 

 about the same as Illinois, and crops can be grown with- 

 out irrigation. The total precipitation diminishes grad- 

 ually toward the sea, until, in the lowest zone, the 

 mean, rainfall is 1Q1/2 inches. 



On this slope there are about 600,000 acres of till- 

 * able land, much of which is very rich and productive. 



The executive committee of the National 



Irrigation Irrigation Congress, which is to be held 



Congress. at Sacramento, Cal., in September or 



October of this year, are actively at work 



making preparations for that event. 



Mr. W. A. Beard, chairman of the executive com- 

 mittee, informs us that funds are now being collected 

 with which to properly advertise the congress and en- 

 tertain delegates who will attend. It is expected that 

 fully 5,000 delegates will attend this congress, owing to 

 the fact that a greater effort than has ever been put 

 forth before will be made to secure a large attendance. 

 Sacramento, as well as the whole State of California, 

 will do all possible to secure a large attendance of dele- 

 gates from the Eastern and Central States, hoping 

 thereby to be able to demonstrate the great possibilities 

 for home-making and commercially, in the State of 

 California. 



An effort will be made to have the governors of 

 each State appoint a full quota of delegates and this 

 fact will be brought to trie attention of each executive, 

 so that the committee may be fairly well assured that 

 all delegates named will attend. 



The appointing of the delegates from the Eastern 

 and Central States has heretofore been made in a sort 

 of slip-shod manner, and there was no definite knowl- 

 edge in connection with the appointment as to whether 

 they were interested in irrigation, or would take an 

 interest and attend the congress. 



As stated before, the committee will depend upon 

 the governors to give the matter careful consideration 

 and appoint only those who express a desire or willing- 

 ness to attend.
