It gave me the greatest pleasure, my dear Annie, to hear that your husband is so well pleased with the improvement produced by the removal of the Scotch pines, that he wishes you to follow my advice in other things, and that you have actually ordered furniture for your morning room in accordance with my suggestions. You ask, however, why I have said nothing of your husband's business-room, and add that you suppose I forgot it; but this was far from being the case. The reason I omitted it was, that I wished, if he asked your opinion respecting it, you might be able to speak entirely from your own feelings, and not from the advice of another. No female friend should ever, on any account, interfere between a man and his wife. In any matter that falls within your own province, I shall always be delighted to give you the best advice I can, but that is all. Should any quarrels arise between you and your husband, (and it would be very strange, indeed, if there should not,) your best plan is to keep them entirely to yourself, and never to ask advice respecting them from any friend whatever. But to return to your house. I was very much surprised to find that you were annoyed with flies, till I read "notwithstanding all the pains our careful housemaid takes to catch them with saucers of sugar and water." This explained the mystery. It is the saucers of sugar and water that attract the flies, and, indeed, one half of what are called remedies for these little pests only increase the nuisance. Besides, without pretending to any morbid sensibility, I must confess that I always think the sight of the poor flies struggling to get out of the liquid grave into which they have been entrapped extremely painful to the feelings. I know it is a law of nature that all creatures should prey upon each other; but I do not like killing creatures by wholesale, when there appears no absolute necessity for so doing. I think if you remove your sugar and water, your flies will disappear of themselves; and, if they do not, you must, in such rooms as are lighted from one side only, adopt our kind friend Mr. Spence's admirable plan of putting network over the window-frame, so that whenever the window is opened, either at the top or the bottom, the space is still covered with the net. You will be astonished to see how efficacious this simple plan is; as, though the flies could easily get through the meshes, they are afraid of trying, lest they should be entrapped.
