2. Malaria is transmitted from man to man only by the bite of _ 
certain kinds of mosquitoes, which are common in the southern part 
of the state. 
3. The larvae of these mosquitoes are found in all kinds of waters, 
but are most abundant in a fairly clean still water with an abundance of 
grass and weeds for their protection. 
4. Control measures are (1) the drainage of breeding-places; (2) 
keeping the margins clear of vegetation; (3) maintaining a film of oil 
upon the water; (4) the use of larvicides for killing the larvae; and (5) 
the screening of houses. Additional, but much inferior, measures are 
(6) the fumigation of rooms to destroy adult mosquitoes ; and (7) the use 
of repellents to drive them away. Palliatives may be used to diminish the 
effect of their bites.
