The time of oviposition varies with the number laid. 

 In one case it was six weeks, the number of eggs being 

 very large. 



The period of incubation varies. In cases noted it 

 may be put down as between 23 and 51 days. 

 (6). All the good eggs are hatched by about October, 

 but the young do not increase greatly in size at first. 

 The period of vitality of the eggs is short, and any 

 remaining unhatched speedily dry up. 

 (7) The young ticks born in the autumn spend the winter 

 months huddled together in the vegetation of the 

 pasture, probably at the roots of the old dead grass. 

 It will naturally follow that the keeping of the pastures 

 clean, either by burning or, much better, by cutting or feeding, 

 will aim a severe blow at the young ticks, but a consideration 

 of remedies I propose to leave, fur want of space, to a later 

 number of this journal, when the very similar large ticks of 

 the Cape, South America, India and elsewhere will be referred 

 to. — C. A. Barber, M.A., in Leeward Islands' Agricultural
