258 Principles of Plant Culture. 
446. Those Who Improve Plants are True Benefac- 
tors. He who produces fruits or flowers for others works a 
transient good. But he who produces a variety of fruit or 
flower that is superior to any now known confers upon his 
race a permanent good. Until the introduction of the Wil- 
son strawberry, the markets of our country were not sup- 
plied with this delicious and wholesome fruit, because no 
known variety was sufficiently productive to be generally 
profitable, or sufficiently firm to endure long carriage. What 
a blessing was conferred upon us by a Mr. John Wilson, of 
Albany, N. Y., of whom little appears to be known except 
his name! There are wild fruits in our copses to-day 
scarcely less promising than was the strawberry of our fields 
a century ago, and in many of our fruits now under culture, 
the development of superior varieties would greatly enhance 
their value. “The harvest truly is great, but the laborers 
are few.”
