fourth plant in the row a Jessie, the latter being used for 

 fertilizing. The plots were laid out 115 feet long and 12 

 feet wide, three rows to a plot, two plots being irrigated 

 and two not. Two rows were left between plots, which 

 were not included in the experiment, in order to thoroughly 

 separate the irrigated from the non-irrigated sections. The 

 plots were irrigated as often as seemed necessary to get good 

 commercial results. 



Comparative Yields, in Quarts, on Irrigated and Non- 

 irrigated Plots of /Strawberries, 1895. 



The yield on the two irrigated plots was at the rate of 

 5,318 quarts per acre, and on the two non-irrigated at the 

 rate of 2,083 quarts. 



Water was used on the irrigated plots on June 10, 15, 

 18 and 20. The water was applied by means of 2 inch hose 

 from a 2^ inch iron pipe laid on the surface of the ground. 

 The size of the stream and the force of the water was 

 sufficient to give 30 gallons (about 1 barrel) per minute. 

 At this rate of flow one man could sprinkle about 1 acre 

 per day. The ground was given a thorough wetting each 

 time. 



On June 24 the writer visited the fields, and made the 

 following notes : ' ' Plants on non-irrigated plots are drying 

 badly ; leaves shrivelled, and many dry and dead ; fruit 

 small, dark-colored when ripe, and shrivelled and seedy ; 

 fruit looks over-ripe when picked. The darker color is 

 probably due to the increased sunlight that the fruit gets, 

 owing to the shrivelled condition of the plants. Plants on 

 the irrigated plots look fresh and vigorous, fruit large and 

 abundant, much green fruit continuing to develop ; size of
