have been a similar rise in numbers of other species of aphids. 
This was distinctly not the case. The melon aphis, for example, 
was much less destructive than usual. Furthermore if this 
new aphis has been with us for many years is seems strange 
that the outbreak should have had a definite center of origin, 
near Tampa, from which it spread out in all directions. One 
would have expected the outbreak to have been simultaneous 
over at least most of the citrus belt. 
MOSQUITO SURVEY OF BAMBOO KEY, FLORIDA

conditions existing there. 
In July 1923, Dr. Howard received another letter regarding 
Bamboo Key from a Mr. S. C. Singleton of Miami, Florida. He 
wrote as follows: ‘There is a smail island called Bamboo Key, 
about a half mile north of Key Vaca, and about midway of its 
length, that is immune from mosquitoes. I am aware of the 
fact that this will sound a bit like a crank story, but if you wish, 
what I say can be supported by affidavits from others. I took 
up a homestead on Ramrod Key; I am not talking hearsay. If 
what I say is so, then few matters are better worth your atten- 
tion. 
Right now, when from here to Key West, the mosquitoes are 
plain hell, and swarminng in the cockpit and cabin of your boat, 
you can anchor close to this island and they will leave your
