a manner that it can be easily turned at any angle. A valve admits 

 water to each pipe. Each line is supposed to water 25 feet on either 

 side, and after one side is watered the pipe is revolved until the 

 streams of water are at the proper angle for watering the other side. 

 The water by the time it reaches the ground is in the form of a fine 

 spray. 



The 250-foot lengths of pipe are composed of 100 feet of IJ-inch 

 pipe, 75 feet of 1-inch, and 75 feet of three-fourths-inch pipe. The 750- 

 foot lengths are composed of 320 feet of 1^-inch pipe, 240 feet of 1-inch 

 pipe, and 190 feet of three-fourths-inch pipe. The small brass plugs, as 

 well as the special drill provided with spirit level for boring holes in the 

 same so as to have them in line, are both patented. The drill with 

 spirit level sells for $10 and the brass plugs for 3 cents each. The 

 measured discharge from one brass plug was 0.3 gallon per minute. 

 In normal operation, one line of pipe will irrigate a space 50 feet in 

 width in nine hours' run. This would correspond to a depth of 

 irrigation of 1.3 inches. At its normal rate of operation, the pump 

 is used to supply 9 lines 250 feet in length, or 2,250 feet of pipe, or 

 2i acres. This would correspond to a rate of flow from the pump 

 of 1 69 gallons per minute. If desired, the pump could be run at double 

 this capacity. All pipe in use throughout the plant is galvanized. 

 The well water being clear, no trouble has yet been experienced with 

 the small outlets in the brass plugs stopping up. 



The irrigation season lasts from the middle of April to the middle 

 of October. The crops irrigated are flowers and strawberries. In 

 dry weather they receive an irrigation every ten days, but they usually 

 require not more than three irrigations per season. Irrigation is cer- 

 ried on, as a rule, between 7 p. m. and 4 a. m., in order to avoid scalding 

 the crops and baking the ground. From 1.1 acres of irrigated land, 

 where 91,000 plants were set out, 89,600 good potted plants were 

 obtained, and from unirrigated land in former seasons not over 60,000 

 plants. As the value is $25 per thousand, this represents a gain of 

 about $750 from irrigation. 



No. 21 . T. R. Hunt, of Hunterdon County, irrigates 6 acres planted 

 in celery, strawberries, cabbage, and potatoes. The land was not 

 irrigated in 1905, the pump cylinder having been cracked bj' freezing. 

 A 3-horsepower gasoline engine drives a double-acting pump, deliver- 

 ing 30 gallons per minute. Water is taken from a pond and elevated 

 20 feet, the discharge pipe being 2 inches in diameter and 400 feet 

 long. The cost of the engine was $225 and the cost of the entire 

 plant $600. One and one-half gallons of gasoline are sufficient to 

 operate the plant for ten hours. 



The soil is a claj^ gravel loam 12 inches in depth, with a clay subsoil. 

 The furrow system of irrigation is used, the furrows being 350 feet 

 long and 3^ feet apart. The furrows are run on a steep grade and
