text: im doing a book summary and theres this wierd sentence that i dont understand...? well after yesterays rain there will be too much brown in the water. what does the word brown mean in the sentence? does it mean afteer yesterdays rain there will be too much mud in the water? if the book was written 50 years ago, then yes, 'mud' is the answer.  if it is contemporary (within the last 10 to 20 years), then browning refers to pollution and acid rain....
