NOTES AND QUERIES.

Questions for reply in coming issue to be IP •sired not later than SATURDAY night. Questions will NOT be replied to through the poet.

Thirty-five Years’ Subscriber asks (1) how to make candied, peel ; (2) what colouring to put in whitewash to make it cream. halves or quarters. Prepare a strong syrup of white sugar and water, put the peels into it, and keep boiling until the syrup is nearly reduced. After this, take them out and set them to dry with the outer skin downwards. Another method is to take out the pulp, soak the rinds for six days in salt and water, and' afterwards * boil them till tender in spring water. Drain on a sieve and make a thin syrup of sugar and water. Boil the peels in it till the syrup begins to candy about them. Take" out, grate fine sugar oyer them and dry them. (2) Colouring powders can be procured from any oil and colour merchant, and if you wrote stating ; your requirements they could supply you with any colour desired. Constant Reader asks (1) where to apply for a birth certificate from the Homeland; (2) the cost incurred. —■ —(1) Certificates of birth can be obtained from General Register Office, Somerset House, London. These apply to England and Wales. The registration exists at Somerset House w from 1837. (2) The fee amounts to 3s 7d — viz., Is for search, 2s Gd for certificate, and Id for the stamp affixed. Browns asks (1) the oorrect pronunciation of "Hohenzollern and if the accent is on the second' syllable; (2) a recipe'for boiled j dressing for salad. (1) Hohenzollern is | Ho-en-tsol-lern, the accent on the first j syllable and the first "o" pronounced as | in note, poke. (2) Whisk the yolks of j six eggs; add to them one dessertspoonful 1 of made mustard, one saltspoonful of salt, a pinch of cayenne, stirring all the time, i Put them into an enamelled saucepan, then j - add a quarter of a pint of salad oil, ■ whisking all the time; next a quarter of a j pint of inilk or cream, one tablespoonful i of vinegar, and the same of Worcestershire : sauce. Last add a pint of vinegar. Continue to stir gently all the time you are mixing, or the sauce will curdle. Now put the saucepan over a slow fire and whisk until the mixture becomes thick. It must not boil. Take off the fire, continue stirring gentlv till it cools. Put it into widemouthed bottles, cork closely, and it will keep two or three montlis. Perfume, asks for a recipe for pot-pourri. The following is*- a good recipe for making pot-pourri: —Gather the roses in dry weather, and in the morning when the sun is on them. Place the petals on trays to dry where there is plenty of air, but no sun. When they are quite dry place m a jar, and for every Mb of leaves add loOz of orris root, Joz. of . cloves, a few blades of mace, and lavender flowers if liked. Shut the mixture up in a pot-pourri jar, and before doing sg moisten with eau-de-Cologne, stirring well. The jar should l>e opened at intervals, then tightly closed! again. Another method is to use loz orris root, loz vanilla, loz cinnamon hark, loz cloves, 10 drops oil of lavender, 10 drons oil of neroli. The oil of neroli may be unprocurable, hut it can be dispensed with. Bronciio Billy asks in the event of best two-wheeled turn-out, to be driven in ring, two competitors were equal in general points, would a judge award the r>rize to competitor using kicking straps? (2) Is a kicking strap considered part of a complete set of harness? (1) It would depend upon the judge and general behaviour of the horse, and in a cl~ e e contest no doubt the tnv--nit without kicking strap would win. (2) No. A. M. (Croydon). Inquiries have failed to locate the agent for the Forttina Separator Novice —<11 The higher the pole the better will l>e the results. If you can have it 29 feet it will give good results; 30 feet will be a big improvement, and so on. (2) The crystal or any other part connected with radio outfit can lv* procured from the British Electric Engineering Co., Moray place, Dunedin. A. H. (Pukerau). — Advance did not win the New Zealand Cup, but in 1900 won the Canterbury Cun.

J. B. (Ri^ersdak).—Mr H. M. Davey, consuiting engineer, 97 Frederick street, replies:—The power of a head of water at 16 feet fall depends to a certain extent on the motor you use. Now, usually a pelton wheel gives the highest power, and is one of the cheapest and most reliable motors, but, although no doubt it would work at that fall, it would not be as effective as, say, a low pressure turbine, but it might be about as effective as a water wheel. However, as makers do not list it at such low falls, it might be better to use either the turbine or wheel, which are listed at your fall. That being tne case, you should get a full B-H. power, a 1 h and a 24 horse-power respectively with 1, 14, and 2 heads ef water. There are so many makes of turbines, from the highest falls to the lowest, that, without ' knowing the make, the number of revolutions could not be stated, but anyhow there would not be very many per minute at that fall. You might get about 500 revolutions with a small diameter turbine, and, of course, fewer with a turbine ot greater diameter. H. J. B. (Southbrook).— Mr H. M. Davey replies: —You have omitted! to state the point of "cut-off” of the steam in y° u otherwise correct description. You will at once realise that this is important. However, since you state the reason of the questions you ask, it would he far more satisfactory if you got a competent engineer to obtain your brake, or actual horsepower. You must consider your exac. position; you must know, for instance, whether you have ample poweT and to spare, or whether you have barely or scarcely enough power at present. engine may be faulty; it may not have the pistons tight; but that would not matter, you could find out the power you have (including all faults, if any) and that would give the electrician a better idea m every way than any amount of calculation which merely tells you what power y°' l ought to have, perhaps not exactly what you have got at the present moment. If, however, you want calculations, send the present “cut-off.” Mr XI. M. Davey writes:—l noticed in the Otago Daily Times of (I think) Tuesday last an old fallacy that is continually' cropping up. It was that a person is lighter after a heavy meal than he was before it. Now that, like many other assertions that crop up is partially true; but there is something omitted in the statement to complete it. The real facts, X believe, were that in a large hotel in America, a few seats were provided as, an inducement to gather more custom, tliat were certainly unique. The seats in question were on the arm of a scale, and were provided with a small table, on -which everything for a meal was placed, both food and drink. The man then took his seat, and weights were placed on the other pan to exactly balance him, his seat, table and food. As he ate and drank, the scale ascend-ed with *1 ii: il and the weights went down. What was demonstrated was, that in taking food and drink, air was expelled and air was thus shown to weigh something. The man with the food inside him was a little lighter than the man with it all before him; but, of course, he liimself was heavier by nearly (but not quite) the weight of what he had partaken. It is as well, perhaps, to add that,, if anyone likes to try this, the scales must be very sensitive, as obviously the difference in weight is very small. Constant Readeb asks for a recipe for bread made with compressed yeast. One quartern of best flour (a quartern weighs and will make a loaf 4lb 6oz), Joz of compressed yeast, one teaspoonful salt, 11 pints of warm water. Mix all into a dough in an earthen basin, cover with a thick cloth, stand in a warm corner of the kitchen, and let it rise for two or three hours. Knead it up well, put in two baking tins, and bake in a brisk oven. Tennis.— We are not aware of any concrete tennis courts in use in New Zealand, the reason attributed being that there would be no resilience, and another cause would be the great cost of laying same. There woqld not. be the spring there is in asphalt and the courts wculd Toe too dead.
