I was never more stimulated to swim in my life.

My ten or fifteen feet dive took me into colder water than I had ever experienced before and I felt as if suddenly, and at one fell swoop, I were flayed alive.

Gasping for breath I made for the boat, climbed in, and in the delicious glow that came with the reaction decided that it was quite as important to feel of the temperature of lake water before you leaped, as it was to render yourself safe from sinking by anchoring yourself to a clothesline.
But I would not have my reader assume from the recital of this experience that Lake Tahoe is always too cold for swimming.

Such is not the case.

Indeed in June, July, August and September the swimming is delightful to those who enjoy "the cool, silver shock of the plunge in a pool's living water," that Browning's _Saul_ so vividly pictures for us.
