Show KILLING OFF THE MOSQUITO Much Has Been Done With Ciude Petroleum, and the Fish Experiment Experi-ment Works Well. According to Ihose who have given much time to tho question of destroying destroy-ing tho mosquito, considerable progress prog-ress baa beeu made In that direction In tfie last few years. Many of tho breeding places have been wiped out In New Jersey nnd Staten island, but unfortunately enough still remain to glvo the Insects plonty of chanco to multiply. Crude petroleum has been jsed with good effect In places where the drainage Is bad, but this, of course, can bring only a temporary cessation of breeding The fish experiment Is said to have beon used successfully In the Barbados Barba-dos All the swumps and ponds were stocked some years ago with a species spe-cies o fish that feed on the larvae of the mosquito. These fishes multiply rapidly and thrive In tho Wost Indian In-dian waters In a short tlmo thero were millions or them In the swamps and pponds, and It was observed that mosqultos were comparatively scarce In the Islands. The success of this experiment led to the stocking of standing waters la Jamaica a yoar or two ago, and the health authorities of that Island report re-port n considerable diminution of fever fe-ver as a result of the destruction of tho mosquito larvae, |
