hoppers. In Series C, tomato at standard rate shows 137 hoppers 
whereas at the double rate only 105 were recorded. Half and half bran 
and sawdust with orange at the standard rate has 82 hoppers recorded 
whereas the same mixture with the rate doubled also has 82. Cante- 
loupe at the standard formula rate in Series D has a total of 100 grass¬ 
hoppers while the same combination with the canteloupe doubled has a 
total of 91. When the proportion of watermelon was doubled in the 
same series the records show a gain from 113 to 134. In Series E 
multiplying the proportion of canteloupe by seven (compare 77, 87 
and 97 with 78, 79 and 80) at first appears to have given appreciable 
results, the smaller amounts of the fruit showing a total of 131 hoppers 
and the large amounts 198, an increase of 51 per cent. This apparent 
gain is probably due for the most part to the canteloupe combination 
at the standard rate having an unexpectedly low record. It is evident 
that these experiments are of only indirect value in indicating the 
amount of fruits of the various kinds which can be used with advantage 
in grasshopper baits. 
Molasses 
Grouping all of the experiments in each series which can be compared 
with regard to molasses 1 we find the results summarized in the follow¬ 
ing table:

It will be noted that the baits with molasses lead three times and 
the baits without molasses lead three times. The difference in the 
totals is negligible, being less than one half of one per cent. 
A comparison of citrus fruit baits with and without molasses is of 
special interest. Both lemon and orange baits have better records 
where no molasses was used, the figures being 340 and 269 for the lemon 
baits and 408 and 316 for the orange baits. Both citrus fruits com- 
1 The molasses known as “Black Strap” was used in all cases where indicated.
