Flies and tiny mosquitoes stick fast to the paper and disturb me. I blow at them to get rid of them--blow harder and harder; to no purpose, the little pests throw themselves on their backs, make themselves heavy, and fight against me until their slender legs bend. They are not to be moved from the spot; they find something to hook on to, set their heels against a comma or an unevenness in the paper, or stand immovably still until they themselves think fit to go their way.
