In Chapter Two the reality of being on a desert island without adult supervision becomes more apparent to the boys. Previously it had all seemed like a wonderful, glorious adventure, the realisation of a dream where life could be lived in boundless freedom in a tropical paradise. This is evident in the youthful enthusiasm that Ralph, Jack and Simon exhibit as they first explore the island, rolling boulders down hills and making plans to draw maps. Upon returning to the group of boys however, things start to go wrong.
At the meeting at the start of Chapter Two there is discussion for the first time about the fear of some kind of snake 'beast' on the island. It causes some uneasiness and foreshadows even worst fears to come. This suddenly switches to wild enthusiasm for starting a signal fire. Whilst the problem of having no means to actually start the fire is resourcefully overcome, it is apparent to the reader that the boys are directionless in creating the fire in a controlled manner. This vulnerability of youth without adult supervision becomes increasingly significant throughout the novel.
As might be expected for a fire lit in the open with no safeguards, it burns out of control. As the fire rages the enormity of its destruction and the terrifying images it creates has a very sobering effect on the boys,
A tree exploded in the fire like a bomb. Tall swathes of creepers rose for a moment into view, agonized, and went down again. The little boys screamed at them.
"Snakes! Snakes! Look at the snakes!" (p.60)
With a muted sense of horror the older boys realise that at least one of the younger boys has been consumed in the blaze as a result of their lack of care.
Therefore, a thesis statement for a piece for writing on Chapter Two might be that the boys discover that their island adventure is not all that it appears to be at first glance, freedom still needs to have its boundaries and responsibility has to be exercised. At this point however the reader may well ask will the leadership group be able to enforce boundaries or to exercise effective responsibility?
