Travel writing analysis

The writer heavily fixes the reader's attention to the fact that the jungle is bursting with life; even when the tired travellers are ready to sleep. He continually describes the ants which are pestering him as he tries to sleep as if they are similar to a liquid (in terms of their movement and sheer volume). '...dark ants poured down...'. The writer says this in hope that it will allow the reader to make sense of how many ants there truly were around the author in this situation. This verb also gives the impression that there were so many ants that the amount of them was comparable to a constantly flowing stream. The writer yet again compares the ants to a liquid when he writes '...I brushed the first wave off...'. This constant comparison allows the reader to deduce that the ants are difficult to get rid of (as is water if one falls into it), as well as that there seems to be a never ending flow of the elephant ants with '...massive pincers...'.
