NOTES AND QUERIES.

Question!) for reply in coming Issue to b» !♦■ •drad not later than SATURDAY night. Questions will NOT be replied to the post. G. B.—The Auckland Industrial and Mining Exhibition was opened on December 1, 1898. Cttrious. —(1) Members of Land Boards are paid 15s per day, with a. travelling • allowj , ance of 6d per mile one way. (2) The three Government nominees are appointed by the Government. (3) The duration of the appointments is for two years. Interested. —The- regulation respecting probationers' uniforms in public hospitals differs in each institution. For example, the regulations at the Otago Public Hospital provide for the supplying (not the the making) of material for two dresses per annum during the four years' course. X. Y. Z.—The. marksman's badge is not issued to the New Zealand Expeditionary Force, but to the Territorials. It consists of two crossed rifles, and is worn on the left sleeve of the uniform. (2) It is not possible to state with any degree of accuracy how long it takes for the effects of a soldier who has baen killed in action to reach his next of kin in New Zealand. All depends upon the shipping facilities; but generally it takes from two to three months. Personal property of a soldier is first sent to the Headquarters in England, then to the Base Records in New Zealand, which finally forwards the effects to the next of kin. Thei-a is no occasion to make application for a soldier's effects; they are sent direct to the next of kin. There is no. reason why settlement of his affairs should be withheld until production of his pay-book. The final statement of his accounts could be received from the paymaster of the New Zealand Expeditionary Force, Wellington. 'Anxious. —Two years ago a Cadet coidd retain his cadet clothing, with the exception of the belt and strap off the hat, when he transferred to the Territorials; now regulations provide that all Cadet clothing and equipment is to be returned to the officer commanding. In the case of your son, the Cadet uniform may be detained, but it must not be altered ox used for any other purpose. D. E. K. —(1) Letters end parcels addressed to a soldier in France who has been- killed before they arrive there are collected by the postal authorities in France, sent to England, and finally returned to the sender's address in JNew Zealand. In the case of perishable goods, these are distributed where possible to the soldier's mates. (2) Papers "posted to the United States must be forwarded by an authorised agent, such, as in this case, the Otago Daily Times and Witness Co., to ensure delivery. Wants To Know.—There are various dressings on the market specially prepared for razor-stropping. Any dealer will recommend a dressing. Subscriber Ko. 1, Cave.—Mr H. M. Davcy, consulting engineer, replies: "If your pipeline is in good order, well laid, with a good intake, and no sharp bends or other obstructions, etc., you may get from 11 to 12 gallons per minute to your wheel. You do not mention the jwater coming into your reservoir, but from the. above water leaving it you can sec how long the supply

will be likely to last. The small quantity (and if there are faults in the pipe-line the delivei-y will be less) would give you less than half a horse-power; but that might be sufficient for the very small plant (whatever that may really mean) you mention. An Bin diameter wheel would do; but it is not so much the diameter of the wheel that matters as that the buckets should be of a suitable size to take the water. Now, a wheel of that size with the pressure you have might run at from 1400 to 1500 revolutions in the minute; and, supposing it had 12 buckets, you can see the number of buckets that would pass the nozzle per minute, taking the 12 gallons. If the wheel were larger, say, 12in, it would travel slower, but it would have more buckets ; so about the same number of buckets would pass, and so the same sized buckets would generally do. With a larger pip© you would, of course, get more water and have more power."
