He paid a hurried visit to Ferry Farm, where, although he was painfully missed, things went on perfectly well, for no better farmer than Madam Washington could be found in the colony of Virginia. Indeed, George's success at Mount Vernon was due in great measure to applying the sound system in vogue at Ferry Farm to the larger interests at Mount Vernon. Madam Washington's pride in his responsible position at Mount Vernon, and his still greater responsibility as a State surveyor for Lord Fairfax, did much to reconcile her to George's long absences. Deep in her heart she cherished a pride in her eldest son that was one of the master-passions of her life. The extreme respect that George paid her filled her with more satisfaction than the attentions of all the rest of the world. Once only had they clashed—in the matter of the midshipman's warrant. She had won a nominal victory by an appeal to his feelings, but she had no mind after that for any more battles of the sort. So, with tears, but with encouraging smiles, she saw him set forth, in the summer of 1749, upon his second year's work in the wilderness.

[HOW TO MANAGE AN AQUARIUM.]

BY JAMES STEELE.

It is generally supposed that it is necessary to change the water in an aquarium at least once a day; but that is not the case. The true principle on which an aquarium should be conducted is not to change the water at all, but so to aerate and refresh the original supply as to maintain it always in a pure and perfect state. There are several means by which this may be done. The healthy growth of plants is very important, and active and brisk contact with the air of the atmosphere will greatly freshen the water. Motion in the water is absolutely necessary. In large aquaria this is obtained by an arrangement of tanks into which the water is pumped, and from which it flows rapidly, circulating through the tanks where the fish live. In its passage through the air it absorbs considerable oxygen, without which no fish can live. Fish placed in water that has been boiled die in a very few minutes.

In a small aquarium the water can be refreshed by frequently drawing it up through a glass or rubber syringe, and squirting it back into the vessel from some height above it.

The first thing to be done in the formation of a fresh-water aquarium is to start your plants in proper soil at the bottom of your tank, fill the tank with water, and leave it undisturbed until the plants begin to grow and the little bubbles of oxygen are to be seen rising to the surface of the water.

Choose your plants from such as you may collect from rivers or brooks or ponds anywhere in the country. Plant them, and then cover the surface of the soil with pebbles and small bits of rock, or anything that is suitable and in keeping with the rest of your arrangements. Never put sea-shells into a fresh-water aquarium, and never put in any artificial objects. Everything should be as simple and natural as you can make it.
