variety should be known before marking out the field. 

 Some sorts, as theWarfield, Dunlap and Crescent, normally- 

 make a large number of runners ; these varieties may be 

 set thirty to thirty-six inches apart in the row, on aver- 

 age soils. Varieties of fair plant-making ability, as 

 the Wilson and Bubach, may be set twenty to thirty 

 inches apart in the row. Some sorts throw out only a 

 few short-jointed runners; these must be set fifteen to 

 twenty inches apart. Glen Mary is an example. Varie- 

 ties which are practically runnerless, as the Pan-Ameri- 

 can, should be set even closer. When the runners 

 either are to be kept off entirely or restricted, the 

 distance between plants in the row is correspondingly 

 shorter. In southern California, Brandywine plants 

 are set six to ten inches apart. On the north Pacific 

 coast, Magoon are set in hills three to four feet apart. 

 These are the two extremes; the average interval in 

 hill training is about one foot. In hedge-row or spaced 

 row training, the most suitable interval between mother 

 plants can be determined quite definitely, as there should 

 be from six to fifteen inches between plants after the 

 runners are set. A heavy, rich soil makes stra,wberries 

 " run to vine." In the territory bordering Puget Sound, 

 a single plant may have a spread of over three feet ; on 

 the Atlantic coast the largest plant may not cover half 

 that space. 



Distance between rows. 



The distance between plants in the rows is determined 

 mainly by envirormiental factors. The distance between 

 rows is determined, to a large extent, by cultural con- 

 venience, although location, soil and variety have some 

 influence. The method of tillage, whether with hand or
