990. _Of the Paste-Board, Rolling-Pin, &c._--After making puddings or pastry, wash your rolling-pin and paste-board, without soap, and put it away quite dry. Never use, nor allow others to use, any of the family dinner or tea-service, in the kitchen; as, if one thing be broken, it would perhaps spoil a valuable set; but, always use for cooking, the plates, dishes, and cups, provided for that purpose, which are usually plain, and though of course equally clean, are much less expensive. Keep the bread, cheese, butter, flour, dripping, milk, eggs, and every thing else you may require in cooking, in their distinct and separate places; and be careful to put them away as soon as you have done with them. 991. _Of keeping Hot Water._--It is highly necessary that you should keep a plentiful supply of hot water, by constantly filling-up the boiler whenever water is taken out of it. A self-acting boiler does not require to be filled, as it fills itself as fast as the water is drawn out; but you must be very careful in frosty weather, to watch whether the water continues to run; for if the water in the pipes becomes frozen, and you allow the boiler to get empty, the consequence is almost sure to be, that when the frost melts, the cold water comes suddenly into the hot boiler, and splits it. The damage can only be repaired by having a new boiler, which costs, perhaps, from ten to twenty-five dollars; so you may see how important it is that you should prevent so serious an accident. 992. _Of Ventilating Rooms._--Do not keep your kitchen always hot, and be sure you let in fresh air. If the attention of every master or mistress of a family turned to the ventilation of their dwelling, it would be greatly the means of insuring health. One single ventilator in the uppermost staircase window, would effect a great deal. Great attention ought to be paid to letting the chamber-windows down from the top, frequently through the day, particularly where the family sits. 993. _Of preparing Tea._--When the tea-time arrives, it is your duty to cut the bread-and-butter, or make the toast. You should never send up more than one or two rounds of buttered toast at once, according to the number to partake of it, that it may be hot and fresh when it is handed round. You must cut off the crusts as close as you can, after it is made and buttered. If a tea-urn is used, it will be your duty to get it ready in time, and put in the boiling water when it is wanted: you must also remember to make the urn-iron red-hot, by putting it into the kitchen fire after dinner, or at least for an hour before tea-time. When you use the tea-urn, be careful to do as follows:--
