spring of the latter just emerged. Allowing four or five days for the eggs to 

 hatch, and about three weeks for the larva to grow to maturity, and ten days 

 more for the pupa state, or about forty days for the whole, which I believe 

 is a good average estimate, and supposing that those which went northward 

 laid their eggs about the 10th of June, the next generation of butterfies would 

 begin to appear about the 20th of July, which fits the facts very well. I am 

 inclined to think that the object of the northward journey is simply to escape 

 the very hoivy rain with which the monsoon opens on the Southern Coast ; 

 but I have always been puzzled to imagine what became of those that went 

 north, and how the population of the south was kept up. This return to the 

 south about Cocoanut Day explains all, for, though I never observed it 

 before, I have no doubt it is an annual event.
