EASTERN FARMERS SHOWN VALUE QF IRRIGATION 



T RRIGATION in the humid regions was given 

 1 fresh impetus at a recent meeting of the Vege- 

 table Growers' Association of America at Philadel- 

 phia, Pa. One day's program was devoted to irriga- 

 tion. The delegates were taken through the truck 

 gardening region of southern New Jersey to the 

 irrigated Seabrook farm. 



Concerning this highly developed piece of 

 ground, the Philadelphia Record says : 



"At the Seabrook farm, which is operated by 

 a stock company, they found a comparative oasis 

 in the midst of the parched and dusty scrub-oak 

 country. The mammoth overhead watering system 

 of the Seabrook farm was patented by a man who 

 found that artificial rain depended only on a gaso- 

 line engine, some good pipes and nozzles that would 

 spray the ground, and it now keeps 78 of the 275 

 acres of the farm free from the fear of drought. A 

 big gas engine, capable of pumping 1,300 gallons of 

 water an hour, sent a spray over the whole plot 

 simultaneously. Sometimes it is called upon to do 

 this for 24 hours in succession, when the germina- 



tion of the seed will bear lots of moisture, and the 

 results, spread out in a huge, symmetrical map of 

 greenery, seemed to indicate that investment and 

 science combined could make of farming just as 

 profitable a venture as of any other business of 

 production." 



In a talk to the association while at the farm, 

 Frederick F. Rockwell, state consulting agricultur- 

 ist of Connecticut, declared : "The regular daily 

 feeding and watering of food plants, just as live- 

 stock is fed and watered, is undoubtedly destined 

 to become a recognized feature of intensive farm- 

 ing in the near future. Under this system the yields 

 of crops will be quadrupled, crops will mature so 

 rapidly that it will be possible to raise more crops 

 in a season than can be attempted at present, and 

 the vegetable grower will be freed from the dread 

 of droughts." 



Mr. Rockwell indorsed overhead irrigation, 

 through a system of pipes rigged on posts, and with 

 spray nozzles at regular intervals, as the best sys- 

 tem he had observed in practice. 



CAMPBELL PATENTS NEW OVERHEAD IRRIGATOR 



T P. CAMPBELL, of Jacksonville, Fla., head of 

 J . the Campbell Automatic Irrigation Sprinkler 

 Company, has just obtained basic patents on a 

 sprinkling system, which he declared will greatly 

 increase the efficiency of the overhead systems. 

 Here is the way a Florida man describes the new 

 machine: 



"If you don't mind getting wet, stand in one 

 place, take a good straight one-quarter inch fire 

 nozzle attached to a one-and one-quarter inch hose, 

 under good water pressure, turn around very slowly, 

 once every two or three minutes, and at the same 

 time slowly raise and lower the nozzle discharge 

 from an almost vertical to a 45-degree position, and 

 in this way you see the exact results obtained from 

 this wonderful little machine. 



"As everyone at all familiar with hydraulics 

 knows, water can be thrown a very long distance 

 from a straight nozzle elevated at an angle of 45 

 degrees, so when the nozzle is at this elevation the 

 water is thrown to an extreme distance, 50 or 75 

 feet, frbm machine used, as it is slowly elevated 

 the intervening area is covered. Anyone who has 

 not seen this particular machine would think that 



to accomplish this result a great deal of machinery 

 would be required, but it is very simple, the entire 

 movement being caused by pressure of the same 

 water that is discharged by the nozzle, the move- 

 ment being caused by reversing rotary valves in a 

 manner claimed to be entirely new." 



The machine shown the writer was equipped 

 with a small discharge tube, and although on only 

 a five-foot stand pipe, covered a circle fully 100 

 feet in diameter and broke the water up so fine that 

 it would not wash or damage the tenderest plants 

 or smallest seeds. The machine weighs less than 

 ten pounds, is very strongly constructed, and even 

 on a very tall stand pipe does not vibrate in the 

 least. 



Mr. Campbell says this new machine will cover 

 about four times the area of the Campbell Auto- 

 matic. 



For grove use this machine can be placed on 

 stand pipes attached to an underground system, and 

 placed 75 to 100 feet apart, extending up through 

 edge of trees so machines will discharge over them, 

 and as anyone can see, by placing a valve in each 

 stand pipe so that only one machine is operated on 

 each lateral pipe at a time, very little pipe would
