Ruskin's note on no.49 reads as follows: 'This wonderful study, one of the most perfect in the series, is done on paper as thin as that of a bank-note. Note how the vermilion on the rocks in the torrent, in the lowest left-hand corner, gives sunshine to all the mass of warm colour in the rest of the foreground. A flock of sheep are passing the bridge; and the [River] Ticino zigzags irregularly through the plains below, leaving logs of pine scattered on its sand-banks. Every way admirable and instructive.'
