Partly touched at Amos's generosity, but more vexed at his present purpose respecting future loans, Walter was not disposed to look with a very favourable eye on his brother's money arrangements.  What could he be wanting with so much?  What could he be doing with it?  There was nothing to show for it.  If he had spent it in guns, or horses, or dogs, or travelling, or sight-seeing, Walter could have better acquiesced in the expenditure.  But the money seemed to be wanted for something which, as far as he could see, turned out to be nothing.  So his curiosity was considerably roused, and he resolved to find out, if he could, where his brother's spare cash went to.
