Two new meth-edg meth-edg of exterminating mosquitoes which have been adopted with great success in Honolulu have been recommended to the New York health department by Ernest Mott Smith, secretary of the Territorial government, who is making his first visit o New York In five years. One of the new methods of combating tho mcsqulto U by tho use of gas while tho other Is the employment em-ployment of mosquito fish. The first method, according to Mr. Smith, was discovered by accident. "We started using oil." he says, "but there was complaint that this gummed up the sewage drains, and then our chief sanitary officer hit upon the use cf calcium carbide. One day In cleaning his automobile lamps, he threw some of the calcium carbide Into an old bucket In which were a lot of embryonic mosquitoes, Tho next morning be discovered that the wig-glers wig-glers were oil dead. "He made some experiments and found that cnlclum carbide was al most as inexpensive as oil and mere effective, so since then wo have been killing mosqultoea by gas. "Then we employ' mosquito fish. They are Utile creatures from an Inch and "a half to two inches Ion? You can take a Jar so black with wlgglers that you cannot see through the water wa-ter and put one of these fish Into it and In half an hour there will not bo a single wlggler outside the fish. The llsh are as transparent as glass when empty, but alter such a meal their bodies are black with the wlgglers they have swallowed. |
