tion and determination of a plan that has promise of success have been 
the preliminary steps. This was done in the case of the citrus canker 
and pink bollworm but these were subjects limited to a single host 
plant and the problem was comparatively simple. The corn borer is 
on an entirely different basis. With respect to the delay, it must be 
remembered that the corn borer has evidently been in this country for 
some ten years and that the risk of spread is now much lessened by 
protecting quarantines which can be and will be strengthened. 
Mr. W. E. Britton: I do not want to criticize, but I would like 
to ask why no scouting will be done in the Mississippi Valley this year. 
I realize that a careful examination cannot be made in all of that terri¬ 
tory, but it seems as though some scouting could be done during the 
winter. It might be possible to determine whether the insect is 
present. It might be found and that would change the plan of work 
for next season, and possibly save considerable time. 
Mr. C. L. Marlatt: The corn borer work for the bureau is in the 
hands of Mr. Walton and the scouting is under the direct charge of 
Mr. Worthley. The reasons for discontinuing scouting I have already 
given in part. These are largely unfavorable winter conditions and 
the economical use of funds. It seems much more desirable with the 
funds as they now are to continue the work next summer when the 
insect will be more easily discoverable. In practically all the new 
territory the insect is so extraordinarily rare that it is very difficult 
to find it in the stalks under winter conditions and it will be easier 
perhaps to detect its early work in the tassel next summer. It is 
largely a matter of using the men and money to the best advantage. 
Furthermore, we are limited as to funds. The $500,000 additional 
appropriation has not yet been granted. 
Adequate quarantines, together with such field and district control 
as is practicable, are the important means of preventing wide jumps 
by the movement of infested products. In such quarantine work the 
states of New York and Massachusetts started valiantly but they have 
not lived up to the promise which this start indicated, a condition 
which has only recently come fully to the knowledge of the board. 
This situation will probably necessitate a federal quarantine and in 
fact a notice of hearing for such quarantine has already been tenta¬ 
tively drawn. The reasons for not taking federal action supplement¬ 
ing the original quarantine as to Massachusetts have already been 
explained. 
Mr. George A. Dean: I have been very much interested in what 
has been said about the introduction of broom corn. Is there any 
way of determining whether the shipments were made in the Mississippi 
Valley? I think some of the states have funds with which they
