Reports made or ivhich you could make specifically for this survey. Are there an^- 

 important or interesting phases of the marine borer infestation which you could 

 report on for the benefit of those who are working on the survey? Ad\ise Mr. Hill 

 about it. Such records or reports should cover, or at least not overlook all the points 

 listed in the questionnaire recently issued, and which were, with slight modification, 

 as follows. (Omitted here; see Appendix B.) 



In addition to the above information (or if that has already been reported, a 

 reference to such report), these reports should give all possible light respecting kind 

 of borer and nature of working (especially by specimens, on which see abo\'e) ; location 

 of working or of marginal and most severe zones of attack, respectiveh", with respect 

 to mud line, low and high tide depth, etc.; as well as nature of exposure with respect 

 to tide currents, fresh water seepage, sewage influx, debris breeding centers, or any 

 other factors which you believe may have affected the life and attack of the borers in 

 the material in question. 



\Vhene\-er possible all reports prepared specially for this survey should be pre- 

 pared in triplicate, so that one copy can be sent to the I'. S. F"orcst Service, Ferry 

 Building, San Francisco, attention of C. L. Hill, and another to Professor C. A. 

 Kofoid, East Hall, University of California, Berkeley, California. 



Miscellaneous observations and notes. — Notes on anything which interests you in 

 respect to the marine borer situation will probably be of interest for the survey, and 

 may be exactly the point missed by others. Dictate memoranda on all such points 

 and send them in to the Forest Service. We can better aiTord to have some such material 

 which is not used than to miss important information by neglecting such notes. 



Photographs. — Good photographs are greatly desired. In no other way can man\- 

 things be told so plainly. Many photographs will be taken in the course of the survey; 

 but if we knew what you had it might save time and money; and you may have a 

 better picture of some important feature than anybody else will ever take. If your 

 collection is not too extensive, can you have copies, carefully labeled, made and sent 

 to Mr. Hill at the Forest Service? If that is not feasible, will you write him about it, 

 so that arrangements can be made to look over your collection and get copies of the 

 items most essential for our purpose?
