I anywhere - in the weedy edges ot brooks, lakes or ponds, in watel standing more than a week in bar. rel, water trough, discarded tins ol crockery, obstructed cave trough COW track, fountain or fish pool, un. screened cistern or well. The egg! of some species float separately (Anopfeles- malaria carrying spe. cies); the eggs of other species (Culex, common domestic mesqui- to, not a carrier or disease) adhere in raft-like masses. In day or two the eggs hatch inco larvae commonly called "wiggle-tails.' Int larvae has to remain at the surface or come to the surface frequently for air; if film of kerosene ol crude oil is sprayed on the surface of the water, the larvae die from suffocation.
 After about a week in the wig gletail stage the mosquito undergoes another transformation, into the pupa. The pupa lies quietly at the surface of the water breathing through a pair of trumpet shaped tubes. In two or three days, or long, CT in cold weather, the pupal stage terminates in the emergence from the pupal case of the adult winged mosquito, through a rent near the breathing tubes.
 This is the natural development of mosquitoes. They never breed in shady places or under weeds ol tall grass or bushes, as too many people imagine. They must have standing water to breed in. The time from laying of eggs to full fledged adult mosquitoes of the next generation is about g days in warm weather, perhaps several times longer in very cold weather Mosquito eggs and larvae will de- velop even after they have been frozen. Some mosquito eggs outlive the winter. Some mosquitoes hiber- nate in sheltered cellars or other out-of -the-way places.
 Applications to exposed skin, oi a dope" consisting of one ounce (abotu two tablespoonfuls) of spir- it's of canphor, the same amount oi oil of citronella and one-half ounce Gone tablespoonful of oil of cedar repels mosquitoes. Better to apply a little of this dope" frequently than much at longer intervals.
 The itching or irritation of mos- quito bites may be relieved by touching the spot with common tincture of iodine, or by rubbing some wet soap on the spot, or by touching the spot with peroxide, or by applying glycerin. or by bathing the bites with a tablespoonful of aromatic spirits of ammonia in four or five tablespoonfuls of wa- ter, or by applying saleratus (bak- ing soda) either in dry powder or as a solution (teaspoonful in half cup of water) on muslin. or other cloths.
 QUESTIONS AND ANSWERS
 Coal Gas
 Our flat is right over water heater burning coal. It causes strong odor of coal gas each time the janitor puts coal on. Is this dangerous to health? Sometimes 1t seems to make me dizzy and weak at the knees, (F. A. W)
 Answer-It Is an intolerable nuisance. 'inexcusable. possibly dan- gerous to health and life. Not the odor, but odorless carbon fionoxide may be given off to the air of the house. Either the janitor does not understand properly adjusting the damper or draft. or perhaps there is a leakage on the stove pipe con. meeting with the flue. which could be readily corrected with c new stove pipe.
