Read it through once

But I am growing unreliable. I will return to my comparison of the lakes. Como is a little deeper than Tahoe, if people here tell the truth. They say it is eighteen hundred feet deep at this point, but it does not look a dead enough blue for that. Tahoe is one thousand five hundred and twenty-five feet deep in the centre, by the state geologist's measurement. They say the great peak opposite this town is five thousand feet high: but I feel sure that three thousand feet of that statement is a good honest lie. The lake is a mile wide, here, and maintains about that width from this point to its northern extremity--which is distant sixteen miles: from here to its southern extremity--say fifteen miles--it is not over half a mile wide in any place, I should think. Its snow-clad mountains one hears so much about are only seen occasionally, and then in the distance, the Alps. Tahoe is from ten to eighteen miles wide, and its mountains shut it in like a wall. Their summits are never free from snow the year round. One thing about it is very strange: it never has even a skim of ice upon its surface, although lakes in the same range of mountains, lying in a lower and warmer temperature, freeze over in winter.
