The Cossacks by Leo Tolstoy

The next day Olénin went alone to the spot where he and the old man startled the stag. Instead of passing round through the gate he climbed over the prickly hedge, as everybody else did, and before he had had time to pull out the thorns that had caught in his coat, his dog, which had run on in front, started two pheasants. He had hardly stepped among the briers when the pheasants began to rise at every step (the old man had not shown him that place the day before as he meant to keep it for shooting from behind the screen). Olénin fired twelve times and killed five pheasants, but clambering after them through the briers he got so fatigued that he was drenched with perspiration. He called off his dog, uncocked his gun, put in a bullet above the small shot, and brushing away the mosquitoes with the wide sleeve of his Circassian coat he went slowly to the spot where they had been the day before. It was however impossible to keep back the dog, who found trails on the very path, and Olénin killed two more pheasants, so that after being detained by this it was getting towards noon before he began to find the place he was looking for.

The day was perfectly clear, calm, and hot. The morning moisture had dried up even in the forest, and myriads of mosquitoes literally covered his face, his back, and his arms. His dog had turned from black to grey, its back being covered with mosquitoes, and so had Olénin's coat through which the insects thrust their stings. Olénin was ready to run away from them and it seemed to him that it was impossible to live in this country in the summer. He was about to go home, but remembering that other people managed to endure such pain he resolved to bear it and gave himself up to be devoured. And strange to say, by noontime the feeling became actually pleasant. He even felt that without this mosquito-filled atmosphere around him, and that mosquito-paste mingled with perspiration which his hand smeared over his face, and that unceasing irritation all over his body, the forest would lose for him some of its character and charm. These myriads of insects were so well suited to that monstrously lavish wild vegetation, these multitudes of birds and beasts which filled the forest, this dark foliage, this hot scented air, these runlets filled with turbid water which everywhere soaked through from the Térek and gurgled here and there under the overhanging leaves, that the very thing which had at first seemed to him dreadful and intolerable now seemed pleasant. After going round the place where yesterday they had found the animal and not finding anything, he felt inclined to rest. The sun stood right above the forest and poured its perpendicular rays down on his back and head whenever he came out into a glade or onto the road.
