makers' purpose, and that the scarcity of suitable wood was such as to make them hoard and make use of every particle. The selection of material was hence considered to be of prime importance by these makers; and by careful study they brought it to a state of great perfection. The knowledge they gained of this vital branch of their art is enveloped in a similar obscurity to that which conceals their famous varnish, and in these branches of Violin manufacture rests the secret of the Italian success, and until it is rediscovered the Cremonese will remain unequalled in the manufacture of Violins. We may now pass to the consideration of the various constituent parts of a Violin. It will be found, if a Violin be taken to pieces, that it is constructed of no less than fifty-eight separate parts, an astonishing number of factors for so small and simple-looking an instrument. The back is made of maple or sycamore, in one or two parts; the belly of the finest quality of Swiss pine, and from a piece usually divided; the sides, like the back, of maple, in six pieces, bent to the required form by means of a heated iron; the linings, which are used to secure the back and belly to the sides, are twelve in number, sometimes made of lime-tree, but also of pine. The bass or sound-bar is of pine, placed under the left foot of the bridge in a slightly oblique position, in order to facilitate the vibrating by giving about the same position as the line of the strings. The divergence is usually one-twelfth of an inch, throughout its entire length of ten inches. It is curious to discover that this system of placing the bar was adopted by Brensius of Bologna, a Viol-maker of the fifteenth century, and by Gasparo da Salo. The later Violin-makers, however, for the most part, do not appear to have followed the example, they having placed it in a straight line, thus leaving the system to be re-discovered. The bar of the Violin not only serves the purpose of strengthening the instrument in that part where the pressure of the bridge is greatest, but forms a portion of the structure at once curious and deeply interesting; it may indeed be called the nervous system of the Violin, so exquisitely sensitive is it to external touch. The slightest alteration in its position will effect such changes in the tone as often to make a good Violin worthless. Those troublesome notes technically known as "wolf notes" by its delicate adjustment are sometimes removed, or passed to intervals where the disagreeable sound is felt with less intensity. Numerous attempts have been made to reduce these features to a philosophy, but the realisation of the coveted discovery appears as distant as ever. The most minute variation in the construction of the instrument necessitates a different treatment of this active agent as regards its conjunction with the bridge; and when it is considered that scarcely two Violins can be found of exactly identical structure,
