60 bushels of wheat; with the best and wisest cultivation and under the
most favorable conditions one can as reasonably hope for one as for the
other. Of this total yield, from 10 to 25 per cent. of the fruit should
be such as, because of earliness and quality, can be sold as extras, and
there is usually from 5 to 10 per cent., and sometimes a much larger per
cent., which should be rejected as unsalable. The selected fruit should
net from $1 to $5 a bushel, the common from 30 to 75 cents--making the
returns for a 200-bushel yield well sold in a nearby market $70 to $350,
and proportionately larger, for a better yield. In practice I have known
of crops which gave a profit above expenses of over $1,000 an acre. This
came, however, from exceptionally favorable conditions and skilled
marketing, and I have known of many more crops where, though the fruit
was equally large and well grown, the profit was less than $100.

In this country a greenhouse is seldom used solely for the growing of
tomatoes, but other crops--such as lettuce--are grown in connection with
the tomatoes, so that it is impracticable to give the cost of
production. As grown at the Ohio state experiment station--and the crop
ripened in late spring or early summer and sold on the market of smaller
cities--greenhouse tomatoes have yielded about two pounds a square foot
of glass and brought an average price of 12 cents per pound. In other
cases yields as high as 10 pounds a foot of glass and an average price
of 40 cents a pound have been reported.

Insects Injurious to the Tomato

By DR. F. H. CHITTENDEN
Bureau of Entomology, U. S. Department of Agriculture

From the time tomato plants are set in the field until the fruit has
ripened they are subject to the attacks of insects which frequently
cause serious injury. On the whole, however, the tomato is not so
susceptible to damage as are some related crops--such as the potato.

=Cutworms.=--Of insects most to be feared and of those which attack the
plants when they are first set out are cutworms of various species. The
grower is as a rule quite too familiar with these insects, and no
description of their methods is necessary, beyond the statement that
they cut off and destroy more than they eat and re-setting is frequently
necessary. The best remedy is a poisoned bait, prepared by dipping
bunches of clover, weeds, or other vegetation in a solution of Paris
green or other arseni
