WILSON'S HYDRAULIC LIME.

,T. Wilson and Co., being the sole agents for this lime, desire to call the attention of engineers, architects, builders, and the public to its many valuable properties, not only aa an ordinary mortar, but as a substitute for Portland cement, in tho erection of concrete buildings, plastering, water tanks, cellar floors, cowsheds, footpaths, &c. It is now about two and a-half years since we opened our yard here for the sale of Wilsons hydraulic lime. Previous to that date; and, for some time after, the trade was" very limited indeed, but now, thanks to the public spirit of a few who had faith in it and to the quality of the lime, we are doing by far the largest lime trade in Auckland. In reply to the report that all Mahurangi Limes are alike, wo would ask those interested to obtain gennine samples direct from the works, and test for themselves, -as, the only satisfactory solution of thispopularerror. "In all cases when an unknown quality of cement is used it is advisable to ascertain,, before undertaking extensive works, . the , exact proportion of sand with which it can safely be mixed, and a very simple, plan for this purpose is to cement several pairs of good bricks together and, after certain intervals, ascertain the amount of force required to separate them. Tho following table will give some idea of the results which" should be obtained by that mode of testing taken from 1 Henry Reid's Treatise on Concrete,'" with Wilson's hydraulic lime added:—

Dear lir,—Having some fruit trees covered with moss ,nd looking very unhealthy, I applied some of your lydraulic limo to them, and it has provod a most lifectual remedy. Tliey are now quito free from noss, and in a healthy condition. -1 used the limo in ,ho Winter months, early in tho morning, when the rees wcro wet with dew.

Messrs Wilson and Co.: Gentlemen,—l have much pleasure in recommending your hydraulic lime as a very suitable and inexpensive material to contract walls, retaining walls, water, tanks, and those buill by your firm on my property-have : given satisfaction.—l remain, Yours truly, Saxi*.- Mobmn.; ■ Grahams town, 10th March, 1880. Messrs. Wilson and Co. : Gentlemen,—l find your ground lime a very superior article, and can confidently recommend any one requiring substantial work to use it. Hoping that the demand will increase, and that you will be able to supply. I remain, yours respectfully, Geo. L. Gixy. Ngaruawahia, April 15th, 18S0. J. Wilson, Esq.: Sir,—ln reply to your enquiry about your lime. As you are aware that I have used some hundreds of ; sacks, I can say without fear of contradiction that it would be hard, if possible, to get any better article both'for concrete and general work or use. In fact I would as soon use it as cement.—Yours faithfully, Robert Lahb. ; * April ICth, 1880. To J. Wilson and Co.: Gentlemen —Having thoroughly satisfied myself after eight months' trial of the reliableness of your concrete flooring 1 intended at once to lay two other floors in my stable and altogether do.away with the asphalt, which I have found to bo no use on a stable fioor subject to the amount of rough use that mine gets. The concrete still remains sound and,solidand appears just as good as when first laid.—Yours, W. Chowther. City Council of Auckland. City Surveyor's Office, September 7th, 1830. Sir,—Your lime concrete water channels, put down for. .the Auckland City Council, have given much satisfaction. When properly put down on a solid foundation, with a reasonable amount of care to allow it set, it wears well, will stand the ordinary cart traffic, and water does not injure it, but rather improves it. .It Is very suitable for flat gradients; being smooth, it enables the water to run off easily, and the channels to be kept clean. I have seen it used in yards where it is subjected to heavy cart traffic without any apparent injury, and on the whole think highly of it. 1 bolievo it would wear well as a sido pavement in hot climates, where asphalt is affected. by heat; it is not slippery, and can be made agreeable to the eye by giving it a light coat of tar. - —Yours respectfully, Wm. Anderson*, City Surveyor. . J. Wilson and Co., Concrete Works, AuckAuckland, September 13,1850.. ' Messrs; J. Wilson and Co., Auckland: • Gentlemen,—l have much pleasure in testifying-to the excellence of the concrete made by you from your Mahurangi hydraulic lime. The floor of the large store at Stanley which you made for me last year has stood remarkably well, and in every respect has given me very great satisfaction.— Yours truly, J. C. Firth. - ■ • •, Queen-street, Auckland, October 18th, 1880. Messrs. Wilson and Co., Mahurangi Hydraulic Lime Merchants : Gentlemen,—l have great pleasure in stating that the three concrete houses you havo erected with your hydraulic ground lime, and under my supervision, have fully come up to my expectations, that they are now without cither flaw or crack of any kindand I consider them quite equal to the cement concrete buildings I havo seen in Auckland. 2nd. For cisterns I have proved it to be both cheap, substantial,'and perfectly'wator-tight. 3rd. For building purposes, and especially for stono work, I consider your lime unequalled, particularly in damp situations. I have seen it sot -very little inferior to Portland cement, and for this' purposo I can Btrongly recommend it as one of the best limes. 4th. The plastering on walls, chimneys, ctc., dono with your lime about twelve months ago is now nearly as hard as Portland cement, and with this advantage, its natural colour is the colour of bath stone. sth. For inside plastering—after the lime has been properly slaked—work done, about twelve months ago is now quite hard, smooth, and free from flaws of any description. 6. For floors or footpoths it is, in my opinion, very nucli superior to asphalting for this climate, both for resisting the action of water and wear of raflio*—-(Signed) Edward JJartlev, Architect. „ ' . . Auckland, 23id October, ISSO. Messrs. >> uson and Co.: Gentlemen,—Your concrote tank holding 3,000 gallons of water has been in constant use, at my dwelling house, North Shore, Devonport, since April 9th, 1879, and is giving much satisfaction. I can recommend it to any that require a good supply of water.—Yours respectfully, Geoiiuk Sibbin*. Great North fioad, Newton, October 26, 18S0. Messrs. Wilson and Co.: Gentlemen,—l have much pleasure in stating that the concrete househunt and plastered for me with your hydraulic lime gives great satisfaction. The walla of the tank (17 x5Jx 5) which abut upon two rooms on the basement, also the concrete flooring 80 sup. yds.) aro quite dry. The tank has contained ten tons in weight of water during the last six months. .The concrete flooring was considered a doubtful experiment, both by tho architect and yourselves, inasmuch as being several feet below the surface it must necessarily rest upon a bed of clay. There is not the slightest shrinkage in any of the walls. These statements may bo verified by anyone desiring to build.—l remain, yours respectfully, John Edwards. Clover Nook, Newmarket, October 2Stli, 1830. Messrs. Wilson and Co.: Gentlemen,—Tho large concrete tank you built for me with " Wilson's hydraulic lime" has given every satisfaction. It has been full of water for about six months, and is perfectly tight and as sound as it was the: day you finished. The fountain and small tauk supplied from the largo one is also in first-class order. I have much pleasure in recommending-you and your lime to anyone requir ing a supply of water from tanks.—'Yours faithfully Charles Stichbury.
