 The New Jersey mosquito, or culeX pungens, which for time out of mind has been considered one of the most ra- venous animals that roves the air, is vigorously defended in bulletins issued by Dr. I. o. Howard, the chief entomol- ogist of the government. Dr. Howard and his assistant entomologists have made a close study of the twenty seven varieties of mosquitoes that inhabit this country, and their conclusion is that the much-abused mosquito that is native and to the manner born in New Jersey is the least harmful of all While &C., EnoWledging that the New Jersey mo- squito is vicious in attack and prolific and long of beak, they contend that. it's bite does not inject poison into the blood of it's unhappy victim, which fills his system with malaria and other dis eases that manifest themselves in fe- vers of more or less intensity and re- currence E..
 It has been determined by Dr. How ard that New Jersey occupies a unique clin1atological and geographical relation to the mosquito family in the United States. Immediately south of the New Jersey line the mosquito families are responsible for all the yellow fever and malaria that afiict the human race. Immediately north of the New Jersey line there is. found another variety of the malaria producing mosquito. But for some reason which the governments scientists have not yet, been able to de- termine, New Jersey is such inhospita- ble territory to the mosquito families on the south and north that they have never been able to get foothold in that ssate.
 The theory that the New Jersey mo- squito guards his frontier and eats up the foreigners as fast as they attempt invasion of the Jersey soil is being care fully studied by Dr. Howard and some of his assistants. If the investigation now in progress proves this tehory to be correct the bureau of ethnology will promptly apprise the world of the im- portant discovery through another bull letin which will enrich the literature on the mosquito subject which the govern ment is fostering through the agricul- tural department. .
 As this is the time of year when city people who are able to go to the coun- try resorts for the summer Dr. How ards bureau is being called on for in- formation as to the habits of 5mosqui- toes in various parts of the nation, and just what their bites do. His investi- gations have demonstrated that mala- ria is not caused by breathing the mil asma of swamps, but that it is contrac- ted only through the bites of mosqui- toes of the genus Anopholes which does not exist in Jersey.
 Broadly speaking" says Dr. How ard "when the blood of human being is sucked into the stomach of a mosqui- to of the genus anopheles the malarial parasite undergoes sexual develop ment and gives birth to large num- Der of minute, spindle-shaped cells, known as blasts, which enter the sali- vary glands of the insect and are eject ed with the poison into the system of the next person bitten by the mosqui- to. If this person happens to be non- malarious the malaria has thus entered his system and malarial symptoms re- suit. So far as present knowledge goes this is the only way in which people become malarious. In order to avoid
