of Newark, N. J.bave made a Yery beautiful improvement in the manulacture of Skates, whicb renders them rar more easy of adjust ment to the root than by the old plan. The improvement consist@ in IJroviding a skeleton ma : iieable iron sole to which the runner is ri vetied or attached by screws, and having two nngs cast on the sole at both sides at the in 'step to supersede tlie old side buckles. A ste· el spring is also attached to the ·sole under the instep 'making the ·skate . elastic with

This is an art for which old Ben West used to be the admiration of all the 'Londoners. ImproTeolentl In a Felloe Cuttlng Ma. ocblne. Messrs. J.L. Adams and L. H. Moores, of Amherst, Mass., gentlemen long 'engaged in the manufacture offelloes for carriage and wa gon wheels, have lately made some very im portant improvements in their macbinery, w bicb enables them to prod uce a fa r greater amount of work and of "puperior character than they could dg heretofore with the sam· e power. Jlaeblne Cor W.ahlne Potatoea. At a late exhibition of the'Smithfield Club, England, 'o we see that a prize was awarded for a . machine which should attract the attention of our farmers. It was a machine for washing polatoes, turaJpa.: euroU�.'l:he r.6Q"t.-to be washed'were placed in a cyllnder madeof spars with an Archimidean screw inside, the whole being partly' immersed in water. The roots were plaeed in fhe cylinder at one end and tbe cylinder revolved in the water nmtil they were clean, when by turning it in tile contrary direction, the washed roots were dis-··charged into a trough at the other end. We hope the hint will not be lost, every labor ' sa ViDg maclrine to the farmer is a benefi t to the whole community. A patent has recen!ly been take� out in England which appears to be a·good one for gas consumers. It consists ora circular valve enclosed in Ii bpx which 'is placed before the burrier'and through which the supply of the gas is furnished to the burner. The burner is a tin plate of brass, perforated in the centre and weighing about fifteen grains;· it is quite loose in the chamber which contains it, and the mode of its operatio)) is this :-When the pressure· of the gas through the chamber does not exceed a certain fiie' d amount, the supply to the burner is such as to·pi'evll· nt any waste {lr smoke, but the moment the pressure ex ceeds this fixed amount, the valve is raised by it to the. top �f the chamber, where, by closing all the' apertures through which the gas is supplied to the burners the supply is at once cut off,-and what gas is requisite to maintain the light rushes tbrough an aperture Jietced in the centre of the vaJve, the size of w blch regulates the consumption. The in . stant the extra pressure diminishes 80 as to allow tbe gravity of the valve to exert its torce, the valve falls back to its first position at the bottom,of th!' chamber .• Impro .... ement In Propeller •• Englrlih' papers say that Sir Thomas Mit chell has made succ�8sfuJ experiments on 11 method of propelling through water by the screw,-which avoids the lateral resistance offered to all existing applications of the in strument j and has lett behind in�tructions for II. patent-which is llOW cempleie.
