Hello everyone.<br/><br/>Please could you explain me a sentence written by Charles Dickens?<br/><br/>Here it is:<br/><br/>Our punch was cooling in an ornamental lake, on whose margin the bower was raised.<br/><br/>What is meant by "was cooling"? Does it mean that the punch was refreshing or that they used the lake to cool the punch? <br/><br/> Thank you in advance.
