THE TOMATO INDUSTRY OF THE ARKANSAS VALLEY. 19 
applied too late, as after the nights become cool watering 
may retard the ripening. 
In the Holbrook country this season were some good 
illustrations of the drouth resisting power of the tomato. 
The last of August I saw large thrifty vines that had been 
watered but twice, once at the time of putting in the field 
and again the first week in August. Where the best re¬ 
sults were secured the land was very retentive of moisture, 
as was also the subsoil, which furnished a small but con¬ 
stant supply. Some of these fields gave promise of ripe 
fruit by early September, yet tomatoes were not market¬ 
ed in quantity until about October 20th. 
INSECTS. 
There are two common insects which trouble this 
crop every year, viz: the tomato worm, (Protoparce celems ) 
and /the corn or boll worm, (Heliothis armigera .) The 
former is very easily controlled by spraying, yet it is sur¬ 
prising how few growers utilize any means of this kind, 
but will put in much time destroying the worm by hand. 
Any of the poisons as commonly used for spraying apple 
trees will be effective against this worm. The best ma¬ 
terial to use is the arsenate of lead for it will not injure 
foliage, no matter in what strength used. 
The latter is the larva of a night flying moth. There 
is no very successful way known of controlling this insect. 
It is sometimes recommended to plant sweet corn near 
the tomatoes as a trap crop. We tried this remedy this 
year with considerable success. It can be said that those 
growing near the corn were nearly free from worms, while 
those at a distance were injured to a considerable extent. 
Three successive plantings of corn should be made, the 
first at the time the tomatoes are set. Each planting 
should be disposed of before the worms get large enough 
to leave the ears. The Hazeltine moth trap was tried 
during the season of 1901 to note if the extent of injury 
could be reduced by this means. The trap was set two 
or three nights in a week and the catch sent to Prof. Gil¬ 
lette for determination. We failed to catch a corn worm 
moth during the season. 
THE SAVING OF SEED. 
A few instances have come under my observation 
where splendid success was obtained from the use of 
home grown seed. The fruit was large and typical of the
