[In this manufactory, as the spent bark is otherwiseuseless, it is employed as fuel for the boiler of a steam-engine which sets in motion the various macliinery em-ployed in the processes of the tannery. The powerexercised by the hydraulic press is used to remove thesuperfluous liquid from the spent bark; and as this stillcontains a small portion of tannin, it is applied afresh.When removed from the press it is as dry as possible, andis immediately fit for use as fuel. The principle of tan-ning adopted is that of filtration; and very strong infu-sions of bark are used, obtained by process of decoction,the water being heated economically, by directing thewaste steam into the infusion-tank.—It.

This instrument offers the following peculiarities :—
1. The reed-stops of the great organ are established ona separate wind-chest, and are supplied with air morehighly compressed than for the other stops.
2. The stop named “Bell Flute,” or “Flute ii Pavilion,”is a recent invention of the builder; the peculiar form ofthe pipes produces a great increase of power, combinedwith the full and melodious quality of sound so indis-pensable in the diapasons.
3. Harmonic flute, a stop in which each pipe gives theoctave of its fundamental sound, as in the upper notes ofthe flute.
4 Cor-Anglais , a free reed-stop of a peculiar form.
5. The stops of the upper keys are enclosed in a swell-box, in order to produce the effects of crescendo anddecrescendo.
6. The swell-stops can be combined with those of thegreat organ in three different ways :—firstly, in unison ;secondly, in octaves above; thirdly, in octaves below.These different combinations are effected by the pneu-matic levers, an apparatus in which the compressed air ofthe bellows adds its pressure to that of the fingers of theperformer, who is thus relieved of four-fifths of the resist-ance which exists in the ordinary constructions. Thissystem has been successfully applied witlun the last tenyears to the principal organs in France .
This instrument is represented in the illustration inthe next page.
