A very successful lady gardener tells us that any one can grow window flowers if he knows how to water them - that "all your rules for this, that or the other, do not amount to a row of pins." Pins! well, bless her dear heart, they are worth ten cents a paper hereabouts, and that is something. Our hints are worth at least as much, and more we think. Still, there is no doubt that a good knowledge of watering is at the bottom of success, and this is what we have always taught. Water must run in readily and run out readily. When a plant is watered, it is a good sign to see it rush out at once into the saucer through the bottom of the pot. If it does not do that, something is wrong. Roots want air as well as water, alternating rapidly with each other. The water drives out the foul air, and when the water is gone, new and fresh air takes the place. So that water has a ventilating duty to perform as well as to actually furnish liquid food for plants. If our dear lady critic were now at our elbow, we fancy we should hear her say after reading this, "Well, I don't know anything about air spaces, or ventilating, or anything of that kind, but I do know when a plant wants water, and then it gets it, and it doesn't get water when it doesn't want.

You see they do just as well as if I could tell a long story about it," - and this is all true. A good shepherd knows his sheep, and his sheep know him. But when the stranger comes among them, he has to observe that the ears of one are a trifle longer than another, the nose of another a trifle sharper, or some slight difference here and there, before he will know anything. Hints are for those who do not know, not for those who do.

Should manure water be given to pot plants? Risking another lesson on practical experience from our excellent lady gardener, we will again go into reasons. Plants like rich food. But the richness of soil is taken up by the water, and carried away. Hence the continual waterings leach the soil, and in time make it very poor. So manure water is excellent in a well drained soil. It restores to the soil in some measure what other waterings have taken away. Yes, use manure water, if your plants are making a thrifty growth. Those with fine, delicate foliage do not require much of it, - coarse-leaved plants, like geraniums and cinerarias, may take a great deal. Guano or the sweepings of a pen or dove-cote, will do well for for the purpose.

"How strong must I make it?" Again our good lady friend would perhaps want to snatch the pen from the writer's fingers, and protest that she knows just how to do it, and never had a hint from anybody, - and so she does. But the beginners may give it too strong; that is, may kill the plants. We can only say, use it so that it colors the water only to the extent that very thin coffee would, - and for a beginning with such articles as we have named, use only as much with the water as you would of coffee for a fair sized family breakfast. Better underdo it at first, until able to read flower language well; then, like the lady gardener cited, no one can learn as experience can teach.

" Shall we use warm water?" It has never been found injurious in any case. Many find no advantage. But cold water keeps back a little the growth of plants. If warm water be used, they will flower sooner. Sometimes pot plants suffer from fungus at the roots, or from insects. Then hot water is of great service. Water at 150šor even hotter, will kill fungus and insects, and in no way injure the roots. Whether plants seem sick or not they are usually benefited by a dose of hot water. But again we dread a lecture from Miss Experience. You may do great injury to some things.

Try lightly at first, and learn by observation just how much the plants will bear. What is one man's meat is another man's poison, - so the household saying goes. • So, with the fair Miss E., we agree that there is nothing does a thing so well as taking right hold and doing it, - and yet we hope these seasonable hints will not be thrown away.
