by the enormous amount of work that the woodpeckers have acccm- 
pl ished. But at the time of his visit, in May and June last year, 
he feels confident that they were not working to any extent on 
the infested trees. He thinks they change their feeding ground 
more or less according to season, and is anxious to obtain informa¬ 
tion on this point. Unfortunately we are unable to give him any 
light on the subject, but I told him I would write you and possibly 
you could supply the missing facts. 
In a few days I shall send you a copy of the list of changes 
and additions to the A. 0. U. Checklist, which T have had prepared 
by Oberholser, and have submitted to Ridgway and others for ad¬ 
ditions. When are you likely to be able to come on here to under¬ 
take the work of revision? 
With best wishes,
