NOTES AND QUERIES.

Questions' for reply in coming istue to be received not later than MONDAY night.

Piping. — Mr.H. M. Davey, consulting engineer, kindly replies: — The fact of the pipe goirg lower than ycur tap, and then rising to it, is not of much consequence. Indeed, :t would not matter practically at all, but for the two elbows, which tend to diminish the output a little. So. as a matter of fact, your fall aincucfe to about 20 in 205J in one case, and about 20 in 210 in. the other. If your taps ere full-way, you ought to get a flow of 1.64 gal from the Jin Itap, and 4.60 gal from the 2> n tap; or, say, a little over ljgal and -ilga-l flow respectively. The sketch helps in ihose matters considerably, and you have given, all dimensions very clearly. Of course, if you could increase your head of water to 25ft, you •woulcJ have slightly more water from your taps. It might be of advantage to you to know that, if one of your taps aid the pipe to it were lin, that tap 'siiould deliver over &s£al per minute. Cabbage Tree. — Will be dealt with by "Agricoia " in "Notes on Rural Topics." D. S. — A tennis court should be 7Sffc long and 27ft wide for the single game, and 36ft long for the double. Cobse Grubber.— No doubt you refer to Findlay's "Havoc Weed Destroyer." If r>o, '.he National Mortgage a.nd Agency Company, Dunedin, will supply you with the information you desire. "W. J. B. — Legally, no one is responsible fcr the natural propensity of the calf. Your best courso is to remove the cow to another paddock, or obtain the agister's permission to fenca in a portion of the lan-d at present used for grazing. Electbo.— The answer to your first qusiy is, No. liIGHTKEEPEB. — There is nothing to prevent an employer form paying £3 a week where an. award fixes the minimum wage at £2 24a a ■week. Gokse. — If gorse has-been proclaimed a poxioas •weed by the local authority, then section 3 of "The Noxious Weeds Act, i 900," 'applies to the case. The words of the section are: — ' Where land abuts on a road', or is intersected by a road; the boundaries of the land on each aide of the road shall, for the purposes of this act, relating to the clearing of noxious weeds, be deemed to be extended to the centre of the road,, and the occupier of the land shall accordingly be deemed to be the occupier of so much of the road as is within «uch extended boundaries." This means* fiimply that the- occupier of land adjoining a road must clear half the width of the road from gorse. If,Jiowever,, gorse ha 9 not-bee» declared, a noxious- weed- by the' locaJ authority, then section 135 of "The Publio Works ~ Act 1894," regulates the mattei. This section provides that the local authority may order the occupier;" or, in case there is- n» occupier, then the owner, of any land abutting upon any road or street, to cut down or grub up, as the local authority may direct^ ancl remove all obstructions to traffic or drainage, arising from the growth of plants (this term means and includes, gorse, sweetbriar, blackberry, acacia, broom, and fennel) upon such road or street, up to the middle line of such road or street, along the whole frontage of the land occupied or owned by him. It has been held by his Honor Mi Justice Denniston, in the case of Bremner v. Dunn (Gazette Law Reports, vol. IV, page 445), that it is immaterial whether the growth lias spread from the land adjacent 'to the road or not. Old Subscriber. — A lias ne lien over B's personal property ; but if B directly excludes A from the use of the net, and denies him the exercise of his rights in relation thereto, then A may bring an action for conversion. To succeed in the action, however, A must prove the manifest sseumption on the part of B of »n exclusive and hostile possession, of the chattel. Constant Reader. — Your specimen came to hand withered and dried up, but it is apparently one of the silenes, of winch the species are very numerous and widely spread ovei the globe. Most of the species go by the name of catchfly. from the sticky substance which covers the leaves. A few ere cultivated foi theii floweis in the garden. Your specimen is the bleddei campion, growing wild on the road sid.s, and it used to be very common about Dunedin. It is of uo value as a farm; product, being merely a weed to be got rid of. — I. M. I. JJ>rjcet Garden Manuring. — Copies sent to J. A. T?., Orepuki; and J. IST., LimehillF. Orders sin;e to hand will be posted to-mor-row.—l. M. I. Propriety. — A. is unquestionably right. The day when women were regarded as only fit to be shielded in a glass case is past, and a much more enlightened view of women's reasoning powers is now prevalent. It seems to U9 that the host's interference was in execrable tasb "C." evidently belongs to a, by- CT one a»e; but :>f course her susceptibilities should ba respected, and nothing said in her presence calculated to give iffence.

IGNORAHTJS.-Mr Davey replies :— ?. itb the amount of water you say you have at your dSposal, and the head, you could scarcely have your wheel over 23ft in d»meter. rhr power" you should get from such a wheel ihould be from 55 to perhaps 52 effective horse-power oify. You ask the diameter or an overshot wheel that would give out 12 horse-

power with the water you mention. It would need to be about 54ft or so. It seems moie than likely that you will n°ed to give more particulars, for with the water and fall you mention, you cannot get the power you I need, and till you explain, it cannot be known whether you can get more water or more fall, or a little of both, easiest. Now, a Pelton wheel witE fully three heads with 40ft pressure would probably give you 'sufficient power ; but you must 3tate what you i can get. With regard to the other questions, the motor and its speed must be de cided on before the sizes of pulleys can be determined. There is no doubt, however, but that a Pelton wheel should be the best for you, or, of course, any quick-speed turbine, as the water-wheel revolving so slowly involves a loss of power as well ps more gearing to drive your machinery at the high speed you mention. Is there any pulley at present on the machine ? If so, what is the diameter and width of it? You will readily see that it is too soon to disctiss the length and size of pipes, seeing that if the conditions cannot be altered you will probably not need any. If, however, you reply to this, state the distance and inclination to your water supply, for from your letter it may be as near as 30ft or it may be miles away. The Bells op Lea. — "Reaiter" writes: — Some few issues back inquiry was made for the words of this poem. Can you say if they were supplied to the inquirer? lam also anxious to secure them, and would feel obliged to anyone who can forward a copy. They do not appear to have been published in any modern 'issues of collections of poems. — We cannot say, as they were to go direct. Possibly the recipient got more than one 1 copy ; if so, will he kindly send us one for " Reciter." D. D. S., Purakanu'i. — We cannot see our way to open our columns to a discussion on ths subject. Country.— Several letters arrived on Tuesday night this week, but that is too late for the current issue. All letters should be in hand by Monday night's mails,, as it is impossible to put anything into type later than Tuesday afternoon. Will correspondents kindly ■ bs-ar this in mind. Subscriber. — You cap sit for examination !, for auxiliaiy-powered vessels, for restricted j areas, driven by other power than that of steam, but you cannot sit for examination for second-class certificate for vessels proi pelled by power other tha-n steam. With i regard to sitting for examination for the ! position of river engineer, the ago limit prohibits you doing so, the minimum age being 21 years. For these certificates al2 months' good character certificate must be forwarded along with other testimonials.
