NOTES AND QUERIES.

Questions for reply in earning istus to bt received not later than MOSfDAY niglU.

I. D.,~~~lnvercargiil. — Mr H. M. Davev, oonsulting engineer, ' 'Moray place kindly replies: — (1) Probably 90 horse-power, as your pipes are on the . small side, loin being a better diameter for that -quantity to be pumped through, as if you pump through too small pipes you force the water so quickly through them* as to cause urirjecessary*"friction. Wit/h the, ' larger size pipes about 83 horse-power should do. (2) Your quantity seems too large for a Cornish plant, aud/tfac lilt too high for the iisual centrifugal pumps., though I believe they are made to pump to "Jie height you need, and if you decide- to use them, inquire again of the •editor. Probably, however, what is termed - a "duplex" pump would lift what you re--quire--- (3) Two-2in. nozzles -will discharge 3J heads -with the head you have, and two Sim-nozzles will discharge 5 heads. (4) Mr pf. B. Hayward, of Messrs? Hayward a.nd Garratt, agents for the "Union", oil engines, rep-lies that an oil engine needs from about, say, three-tenths o^ a, pint per horse-power per hcu_ . for very large engines to> say, three-quaiters of a pint par hcrss-power per hour for small engines. The "Union" engine that gave the "best results was a 60 horse-power one. and -worked at the Wanganui Freezing Works. You could get further particulars from thenr if you want them. ' _&.. C. — Mr Davey replies: — Your paper was left apparently in the jditor's office. It seems to contain the beginnings of a question. You state tihe size of a furnace and

the lengths and number of the tubes, also their diameter, but there is no mow. Please _ say what you require to know. Pontoon. — Mr Davey replies: — The question . was answered, but front some reason or other it appears to have been mislaid somewhere in ther offices of the Witness. You do not mention whether the 10 tons

is to be the weight that the pontoon is t*> carry ov^r and above its own "weight, or ■_ -whether the weight of the pontoon is to be " included, and the -whole is to be 10 tons. Taking this latter as probably being what yor. namely, ten tons displacement, the thing needed is to imagine a, size, as, . you-give no indication of this or the draught yau would like. The will >c - about -360 cubic feet, tfnd so if your punt ".-were" say, 120 ft long^ by, 10ft wide by, say, 3ffc * 6in deep., it. would' work out as follows: Each foot of immersion giving 200 cubic feet, the punt would draw lft 9|in, and the freeboard ; would be lft S|in. If you decide any of the* sizes, etc., now omittsd. and want

any particular draught, write to the editor

a gam. Jl.J 1 . B. (i) Yes, if the local authority ha.ving jurisdiction, by notification published in a newspaper circulating in tlie district, has fixed the fee at 2g 6d. As a matter of fact, it is open to the local authority to reduce the fee to Is per dog. (2) "The Bog Registration Act Amendment Act, ISS2." (3) The form of declaration is as follows: "I, the Tinctersigned (here insert name), being the owner of* — dog (or dogs), which I arxply to have registered under section 2of 'The Dog Registration Acb Amendment Act, 1882/ ibereby solemnly and sincerely deolare that the said dog (or dogs) now is (or are) and ■will be kept for the purpose of the destrwc-

tion of rabbits. "Witness to signature — " C. D.

" day of , 1905." A Shareholder.— Ye3. It is noi. illegal. T. G. — The stick insect is common enough in New Zealand. It belongs to the family Phasmada, and the specimsn you send is Aoanthoderus horridus. It hatches from eggs, and feeds on leaves. The other specimen is the common lizard found all over JSfew Zealand. Subscriber, Gxeymouth. — Mr H. M. Davey replies: — Your question was submitted to Mr P. A. Cooke, of the firm of Messrs Cooke, Howlisoai and Co., au<l he very Ictofllly tn&cfe ■notes on your diagram, -which tha editor will jreturn to you separately. I ihope you will understand the reply, and tha.t it will be useful to you in solving your

difficulty. BcHotLAß.— The information you desire will be found in detail m the New Zea'and University and the Otago University calendais. (1) Candidate for. matriculation must pass

at least seven of the following subjects: — English, arithmetic, algebra, Euclid. Latin, Greek, French, German, history, geography, elementary mechanics,, elementary heat, sound and light, elementary electricity and magnetism, elementary chemistry, elementary chemistry, elementary zoology, elementary botany, music, and drawing. (2) The rnatric examination must be passed before a candidate is allowed to keep terms or to enter for an examination for a degree. A j student can, on payment of the class fees, j attend the lectures. (3) A class fee of 4gs ' must be paid for all practical classes, and ' 3gs for each of the other classes. The cost would therefore depend on the number of ' classes attended. (4) The candidate is ad- | niitted to the iinal examination for the degree i of M.B. whose name has not been on the medical register for at least 51 months previously. A candidate for the degree of M.D. must have obtained the degree of M.B. at least three years previously. (5) No reduction is made for " poor " scholars. Subscriber, Gore. — Mr Davey replies: — Of course in this argument you will at once recognise that the number of gallons is abso- j lutely immaterial to the issue. It seems to some that what they would term " forcing water to water " hinders delivery, and it is better to deliver the water higher than necessary if one can but get an open end to deliver out of. If, as you say, the tank were \ full and the pipe delivering the water to the tank over the level of the water in the , full tank, there would not be much differ- ,' encs — merely that of the diameter of the , pipe in the levels; — so that were the tank 4ft to pump up to and the pipe 6in in

. H., Wairmgton, — The following recipe for elderberry wine appeared a. few weeks ago. As possibly yon may not have the number by you, we reprint it — To 6gal berries add 7gal water, add Jib allspice, 2oz whole ginger, and a few clove? ;' boil this for half an hour, by which time it will be wasted! to 7gal or Sgal ; squeeze the berries well, ard to every gallon add 3Vb moist sugar. The quantity then wi'l be sufficient for a 9gal keg. The Fmgar being added, boil till the liquor becomes clear, taking the scum olf as it rises. Remove it to a cool place, and put it into the cask when lukewarm ; add to it a piece of toasted bread dipped in thick yeast. Should it not start to ferment the next day, a small quantity of wine taken out and made to boil and then replaced in the cask will probably exsite it; if not, another piece of bread), dipped in yeast as before, must be added. Let it remain about a week. When the fermentation has subsided fill up the keg and bung it down closely. It will be fit for use in about three months, but it will keep for years.

. C. E. — The population of Ireland is 4.458,775. . H.— (l) "You" is the plural of 'Mhou,'^ so that there is no need to say " you both " when addressing two persons. There is no such words as " yous." (2) It was debated at the time of the Gregorian calendar whether Easter should continue to be movable or whether a fixed Sunday after the 21st March should be adopted. It was deference to ancient custom that led the ecclesiastical authorities to adhere to the method of determination by the moon. It is, however, an altogether imaginary moon,

site you mention. The land wss bought by the National Bank, and Ihe license was transferred to the building at the corner of Cumberland and Hanover streets still known by the same name." L. E X.— We regret that space will not allow of our doing so. Could you rot arrange ior Thursday's 'Daily Times <o be posted to you every week. If your friends cannot^ do <=;o you could have "it =?nt fiom the office, as the cost would be trifling. Hili.OtPove. — Unquestionably. It should 1 c taken for granted that the letter thus addressed is intended for the son's mother. Gold Digger.— <i; Mr F. O. Bridgeman, .5 Bond street, is the American Consul for Otago. (2) Not unless by special vote. You should wiite to the Minister of Mines, Wellington, and place your case before him. Argument. — The lead is beaten in.
