This may seem an impracticable refinement. It should be remem- 

 bered, however, that bunches of perfect grapes of good shipping 

 qualities can be sold for $50 per ton, while poor grapes are worth

 grapes and the net profits may be ten times as great. Many growers 

 could undoubtedly very much increase their profits by concentrating 

 their labor and expense on half the area they now 7 cultivate.
