NOTES AND QUERIES.

Subsobebbb, Whangarei.— (l) From a report written several years ago, the treatment of the ore of the Oomstook lode (whioh may not have been altered materially since; was as follows:— Ore oruihed nnroasted, wet, by stamps weighing 7001b or 8001b each, and with a drop of 71n or 81n through number 40 screen or wire gauze. The crushed etuff falls into tanks 7ft iquare and 301n deep, from which it is removed to a series of so-called Horn's pans for further grinding, amalgamation, and concentration. These pans (of which no special description Is given) are 6ft in diameter and 32in deep, and have a muller revolving 14 times per minute. They receive ocob a charge of two tons at a time, ana after wot king the oiushed ore (pulp) for three, hours, about 4001b of quicksilver is added to each charge in the form of a thin spray, and then the pan Is worked for another two hours so as to ensure thorough mixing of the quicksilver with the sand, After this the plugs of these pans are successively opened from the top downwards, and the' pulp is run into the so-called •• settler," which is 10ft in diameter and 3ft deep, and in whioh also a muller revolves at a speed of 14 times per minute. The pulp is thinned down by means of jets of pure water as found necessary, and the upper plugs of' the settler are opened to convey away, the waste for a second treatment. The lower plugs are not taken out until the amalgam is clear of all' sand and slimes. The amalgam is conveyed first to the strainer and ultimately to the retort. If' the ore is not working well In the pans, solutions of sulphates of copper and iron are added occasionally, and superheated steam is alio forced through pipes in the bottom of the pans with very satisfactory remits. (3) About cost of this treatment no information is given. Zero.— Mr Beverly replies to your query*— Your question would be a good one for a physical classroom. Its solution depends on the fact that, wJS equal temperatures, the volume of a portion of air varies inversely as the pressure. If the air oooupie» lin of the tube under a pressure of 15in, then the length occupied by it when it reaches the top multiplied by the depression of the barometric reading will evidently equal 15. Let x— the de> pression in inches. Then since the bar. stands at 30, and the tube is 321n long, we have this pro-> portion : As 15 is ' to x \to is x-f-2 to 1, or x*+2z 15. Add Ito eaoh eide to complete the square, and x*+2x+l 16, therefore x+l—4, or x*-3. So that the bar, will resd 80—3: or27in. 8., Oamaru, writes :-^Queen Vlotoria entered the! 55th year of her reign on June 20, having ascended ; . the throne on Jane 20, 1837. Only two sovereigns ■ have reigned longer on the English throne— George ; 111 (69 years) and Henry 111 (58 years). James I ' though be only reigned 22 years over Bngland reigned 67 years and 8 months over Scotland. I subjoin a list of all the sovereigns of Bngland who reigned over 20 years »—

Sbtei.— We are of opinion that he Is qualified. Mioawbbb.— (l) Socialism is the name given to a olass of opinions opposed to the present organisation of society, and which .seeks to introduoe a new distribution of property &°d labour, in whioh organised co-operation rather than oompetitiou should be the dominating prlnoiple, -under the conviction that the happiness of the race, and especially the classes without capital, would' be benefited thereby. <2) It is objected to Socialism under its various forms that it makes human happiness too much dependent on material gratifications; that it robs man of that energy that springs from ambition ; that it nnpbiloiophloally ignores an individualism and inequality to which Nature herself has given her inviolable sanotion: and that by the abolition of social rewards and punishments it neither holds out any hope to the lnflnstrioas, ncr exoltes any apprehension among the indolent.— (" Chambers' Bnoyolopsedia.") (3) Cod liver oil is admitted free of duty. (4) There is a cod liver oil faotory at Port Chalmers. (5) It is said that there is, but we cannot ssy with what degree of truth. Dogs fob Babbiting— "Mioawber" writes:— Will any of your numerous readers, now the rabbiting season is on, let " Micawber " know whioh breed of dogs are the best for carrying poisoned rabbits ; whether any particular breed, or D»mV the best orois, if before the purebred. Expressions of [ opinion are invited from those who have had experience with different breeds of dogs in this work. $ - ' ST. M. M.— We have not the Information at hand but if you write to the Mine* department at I Wellington you will be supplied with it by return mail. Anxious. — The tenancy would be- determinate by I one month's notice in writing. |M. S.— Yes, a post-dated cheque is legal. Inquirer.— (l) No, unless otherwise provided by contract. (2) No, you cannot compel them to have it tested at-their own expense. You can have it tested fly the inspector upon requisition to him and payment of, expenses, (3) The Inspector of Weights and Measures for the district, who we think would be at Invercarglll In your case. (4) See answer to second query. You had better write to the inspector for information. <5) Any person having light weights is' liable to a fine not exceeding £10, and to forfeiture of the weighing machine. Millkb.- (1) Millers' hours are :— Five days, 6 a.m. te 6 p.m., one hour for breakfast and one for dinner ; Saturday, 6 a m.'to 1 p.m., one hour for breakfast. (2) Wages: Boiler millers, £3 to £6: stone milleri , £2 10s to £3 lCs. W. M., Otama.- We are not aware, as they seem to think it right to hide their light under a bnshel. Your query came too late for -inquiries to be made this week. See next issue. Busk.— This correspondent asks : -What are the pieportlont of flour, egg", butter, aud sugar, in order tc make bread from which rusks are to be prepared? Can any reader oblige with the information ? Atiab.— The thinnest bleached calico you can get, and tbin paste well and carefully boiled with a little alum in it.
