NOT QUITE SO DECISIVE AS IT WAS BUT A LITTLE MORE OVERWHELMING. Wj9 CHALLENGE the representative of the Singer Sewing Machine Company, or any of the jurors on Sewing Machines at the Exhibition who voted for the report coming from that body to controvert the following statement of facts. Kfessrs Modelings, Ounnington, Bale, and Kirk, we t call upon you to defend your report, H. O. FISKE & CO. Chrhtchuroh International Exhibition, Juno 15th, 1882. REPORT OF COMMITTEE OF EXPERTS. To H. C. Fiskk & Co. request, we have examined the New Davis and the New Singer Sewing Machines, for the pnrpose of comparing them. In our comparison we have takei into consideration— 1. '1 he mechanical principle involved 2. The quality of the material used 3. The deproe of workmanship exhibited 4. The facility for doing a good and varied OMS of work. After taking both machines asunder, carefully examining every piece, and fully tosting their capabilities, we have no hesitation in saying that we consider the Davis far the superior machine of the two. Our reasons are as follows : In both machines the ssme method is adopted for actuating the needle bar, viz , a orsnk with roller working in a cam. This oam in the Davis Machine is cat out of a solid piece of steel and hardened, while In the Singer it Is not only very much lighter, but is made of common oast iron. The feed apparatus of the two machines are very dissimilar. That of the Singer Is the usual slip feed. The Davis has the vertical feed peculiar to Itself. In this arrangement the presser foot holds the material firmly down till the needle has reached its lowest point. The pressure is then relieved and transmitted to the feed bar. Feed bar, needle, and material are then, by a very simple contrivance, moved forward simultaneously the required length of etitch.

Motion ia giy< n to the shuttle in the Davis machine as follows An eccentric at the wheel end of the main spindle gives motion to a vertical lever. This in tarn transmits it through a ball joint of ingenious constrno tlon to the only moving part nnder the maohine, a pivot, ai lever having at its end an adjustable shuttle carrier. In the Singer Machine a pair of mitre wheels drive a vertical spindle, having at its lower end a orank. A connecting rod from this crank moves a sliding shuttle carrier. It will be seen that in the Davis there are between the main spindle and the shuttle four points of friction, the pivot carrying the vertical lever, the eccentric, the ball joint, and the pivot of horizontal lever. The two principal movements, the eccentric and the ball joint, are adjustable, and the parts most liable to wear are made of hardened steel. To oompsss the same work the Singer employs as points of friction the teeth of the mitre wheels, the two journals of vertical! spindle, the two ends of the connecting rod, and the sliding shuttle carrier None of these plaoes are adjustable. The small wheels are common cast iron, having a certain amount of backlash, and consequent tendemoy to rattle and and break. The connecting rod la a thin bar of iron, with a hole in each end. The end wbioh runs on the crank pin is one of the principal joints in the machine, having a considerable amount of work to do with small bearing surface, making it very liable to wear, while, as before remarked, there are no means of compensating for any wear. It will be notioed that the shuttle of the Singer Maohine is oarried in a slide, to wbioh a lateral strain is given by the driving rod, causing a oertain amount of friction, while in the Davis it is carried by the lever quite free from frlotion. With the exception of the small roller working the needle bar, there is not a single piece in the Singer Maohine, not even excepting the shuttle, that cnunot ba out with an ordinary pocket knife, and there are no means of adjusting any wearing part. In the Davis not only are most of the pieces made of steel, and tempered, but at every essential point means are provided for taking up any wear. On this point we may say that where we had any doubt about the quality of the material employed the the piece was broken and the fracture carefully examined. Having examined the mechanioal arrangements of the two machines, wo tested their adaptability for work, end we noticed the very peouliar faed of the Davis. In this respect wo have been forced to the conclusion that for all purposes, sewin from the thinnest muslin to even throu a metal spoon, the Davis has no paralle grasp, or for avoiding that puckering often the effect of the pressure on a fore motion feed. We must in common honesty expresß our astonishment at the range and variety of work accomplished by the Davis, which we are satisfied cannot be done by the Singer. In summarising our report we repeat that we have no hesitation in laying that we regard the Davis as very superior to the Singer in workmanship, material, and the mechanical principles involved, and also in performing a greater range of work. We found the Davis to work with equal ease from the lightest to the heaviest fabric. JOHN LEE SOOTT (Scott Bros.), Meohanioal Engineer. T. GLUYAS PA3COE, Manager of the Kaiapol Clothing Factory. GEO.

The stock is well assorted, and will be found very complete, and should command the attention of all olaßsea of customers. There is not any similar stook to select from In Christchuroh. The quality of the goods and the lowneas of the prices must commend themselves to all who pay the establishment a visit.
