The bows that accompany the "Hellier" Stradivarius are from the collection of Messrs. Arthur and Alfred Hill. The violin bow, the medium by which the performer's personality is transmitted to the instrument and its various powers are brought out, is not less worthy of admiration than the violin itself. The gradual improvement of the bow has followed the development and improvement of the violin, and the settlement of its form and materials in the last quarter of the last century by François Tourte, in reality made the violin a different instrument from what it had been before. With Tourte's bow came a power of expression in violin-playing previously unknown. [Illustration: XXVI] PLATE XXVI. VIOLINS, THE ALARD STRADIVARIUS, THE KING JOSEPH GUARNERIUS DEL GESÙ. The back and front views of the Violin to the left of this Plate are taken from the "Alard" Stradivarius, so called from the famous violinist who formerly owned it. It is one of the finest violins made by Stradivarius, and bears the date 1715, thus belonging to his great period, which is considered by connoisseurs to have extended from about 1700 to 1725. The following is the brief history of the Alard Stradivarius. Bought in Florence early in the present century by a banker of Courtrai in Belgium, it passed at his death into the possession of the late J.B. Vuillaume of Paris, one of the most famous violin-makers and experts of the present century. Vuillaume reserved it for his son-in-law, Mr. Delphin Alard, professor of the violin at the Paris Conservatoire, and of European reputation as a virtuoso, in whose possession it remained until he retired from public life in 1876. It was then acquired by Mr. David Laurie of Glasgow, in whose possession this fine instrument still remains. It is a Stradivarius of the "grand" form, and of a very handsome model, the arching of the belly and back being of exquisite proportions, neither exaggerated nor weak. The workmanship is between the earlier and later styles of the master. A careful choice of the wood is of course presupposed, but the fine regular marking of the back may be observed, and also the beautiful colour and quality of the varnish. The neck is original, as it left the hands of Stradivarius; it has, however, been lengthened by a piece added at its junction with the upper block of the body. The letters P.S., which are sometimes found on Stradivari violins at the peg-box end of the neck when it is original, are here very distinct. These enigmatical letters have given rise to some discussion among experts, but the conclusion appears to be that they are the initials of Stradivari's youngest son, Paolo, through whose hands the instruments may have passed. Paolo was a cloth merchant, not a violin-maker, but he succeeded to his father's house after the decease of his brothers.
