Read it through once

It appears from Sleeman that in India the occupation of elephant-driver is confined to Mohammedans. I wonder why that is. The water-carrier ['bheestie') is a Mohammedan, but it is said that the reason of that is, that the Hindoo's religion does not allow him to touch the skin of dead kine, and that is what the water-sack is made of; it would defile him. And it doesn't allow him to eat meat; the animal that furnished the meat was murdered, and to take any creature's life is a sin. It is a good and gentle religion, but inconvenient.
