PEDIGREED FIBER FLAX. 



separate. Mr. Crandall continued the selections in this way in 1911 

 and 1912, the field work being carried on at Croswell, Mich., and 

 Crookston, Minn. 



In 1913 Mr. Frank C. Miles took up the work and continued it 

 until the spring of 1917. As a basic stock for selection, strains which 

 had been developed by Mr. Crandall were used, and material was 

 added from imported seed as well as from the commercial fiber- 

 flax fields of Michigan and Oregon. Selection plats were grown 

 by Mr. Miles on the Potomac Flats near Washington, D. C, at 

 Yale, Mich., on the grounds of the Northwestern School of Agri- 

 culture, Crookston, Minn., and at the Oregon Agricultural College,

Corvallis, Oreg. The most important work was carried on at Yale. 

 Improved strains decidedly superior to commercial strains were de- 

 veloped and attempts made to increase the seed, but in three seasons 

 this work was interfered with by disastrous storms at Yale and at 

 Crookston, which practically destroyed the increase plats. 



The flax planted on the Potomac Flats at the Arlington Experi- 

 mental Farm, Va., in 1913 and 1914 made a satisfactory growth and 

 flowered, but it produced very few seeds. Work at this point was 

 therefore discontinued. 



A number of tall plants were grown in the greenhouses at Wash- 

 ington, D. C, during the winter of 1913, and crosses were made be- 

 tween the more promising ones. These crosses were grown to the
