200 feet in length, and after having adjusted the flow, it will require no 

 attention until the ground has been thoroughly wet. As the water will be 

 applied beneath the surface, there will be much less loss from evaporation 

 than when furrows are used, and, consequently, it will be more economical 

 of water, and will permit the covering of a considerable area through a small 

 supply pipe with but little attention. Under the same conditions, the use 

 of furrows would not give nearly as even distribution and would require 

 constant attention. 



FROST. 



(Neiv York Experimental Station Bulletin No. 127-128.) 

 Although frost is continually showing freaks, the injury that is done to 

 blossoms can be greatly lessened if proper care is taken to secure a location 

 with thorough air drainage, which can be best obtained on an elevated 

 rolling site. While this is quite essential in the interior, less attention need 

 be paid to it near the lake shores and along the rivers. When air is well 

 charged with vapour the injury from frost is greatly reduced, and where 

 water is available a crop often can be saved, which would otherwise be 

 destroyed, by sprinkling the plants just at night, or, better yet, very early in 

 the morning, when the temperature drops to 32 degrees. With a supply of 

 hose and an ordinary lawn sprinkler a considerable area can be covered. 



POLLINATION. 



When strawberries are grown in matted rows, each third row should be 

 planted to a staminate, or perfect-flowered variety, to provide for pollination 

 of the flowers, care being taken to plant near together varietites which bloom 

 at the same time. This plan of setting the perfect flowered and pistillate, or 

 imperfect flowered varieties, in separate rows, rather than distributing the 

 staminate plants in the rows of pistillate varieties, is preferred, as it facili- 

 tates separate picking and marketing of the varieties a very important 

 factor in securing ready market and good prices for the berries. 



(Central Experimental Farm Bulletin No. 5.) 



Strawberry blossoms are divided into classes, 1st, bi-sexual or perfect. 

 These contain stamens or male organs and pistils or female organs, as in 

 Figure 5, hence are called perfect or bi-sexual. Second, pistillate or imper- 

 fect, which contain pistils only, or female organs, as in Figure 6. Pistillate 



Fig. 5. Fig. 6. 



varieties usually yield the largest crops of fruit when properly fertilised. 

 This may be done by planting one or two more rows of a perfect-flowering 

 sort to every four or five rows of those with imperfect blossoms.
