Fig, 5. — Comparative yields of the strains of Jersey Wakefield (average for the test). 



shows an almost unbroken row of cabbage which remained in 

 the field when the rows adjoining had been cut and sold at 

 higher prices than prevailed later in the season. In other 

 words, the almost unbroken rows shows a lot of leafy heads, 

 many of which failed to produce marketable heads imtil the 

 market was broken and prices were materially lower. There 

 was also marked variation in the total yield per acre. In 

 the 31 strains the yield per acre varied from 6.93 to 10.70 

 tons. The illustrations (Figs. 6 and 7) show that the varia- 

 tion in other strains is even greater than in the case of the 

 Jersey Wakefield. The results of the extensive experiments 

 at State College indicate that greater care should be exercised 

 in the production of good seed. There is no reason why in- 

 telligent market gardeners should not produce their own seed, 

 and experiments made at State College and elsewhere indi- 

 cate that growers using large quantities of seed of certain 

 classes of vegetables will probably in the near future have all 

 their seeds grown by contract for their particular purposes
