($1,500) was included under general expenses of the Territorial board 

 of health, and reads, ''Plxpenses, importation of lish for destruction 

 of mosquitoes, $1,500.''' 



In accordance with the following letter, Doctor Jordan selected 

 Mr. Alvin Scale to undertake this work: 



Stanford University, Cal., April IS, 1905. 

 Mr. D. L. Van Dine, 



United States Experiment Station, Honolulu, Hawaii. 

 Dear Sir: The best place to collect the fishes which you want would doubtless be in 

 Louisiana. It would probably take no longer time to bring them from there than from 

 other places nearei-. Perhaps an equally good place would be Tampico, on the edge 

 of JMexico. You understand that this would necessarily be an experiment. These 

 little fishes feed freely on mosquitoes. Some live in In-ackish water, some in fresh 

 water, and all of them are very hardy. But no one has ever yet tried to transplant 

 any of them, and the whole thing might turn out, for some reason or other, to be a 

 failure. Especially one would need to experiment on feeding the little fishes during 

 their transportation. The genera which I would recommend are Mollienesia, Adinia, 

 Gambusia, and Fundulus. Some of these are viviparous, others lay eggs. Whoever 

 undertakes this should give a good deal of attention to the question of feeding the 

 little fishes, and for this purpose perhaps a tank breeding mosquitoes would be as 

 good as anything. The best time to undertake it would be about the 1st of June. J 

 will select some one as soon as I hear from you. 



Very truly, yours, David S. Jordan.
