The number of pupils and assistants who worked with or under the supervision of Stradivari in his prime, might, if we knew all, be more considerable than we should be prepared to expect. The proportion in the usual course of nature, of those able to single out a path for themselves, prove their individuality superior to their fellows or eventually become of great eminence, must of necessity have been comparatively small. There may have been many working "on and off" under the eye of the master at different periods who were without ambition or the talent to rise above the position of humble helpers among their more talented brethren, born to be assistants only, and, in consequence, never heard of outside the studio. These, and the before mentioned, must all have had something to do with the instruments their master was sending forth into the world; the more clever ones being intrusted with some responsibility on particular work. It is not impossible to fix upon the parts the assistants probably would be allowed to work upon. In the first place, all the designing, drawing out and tracing down of the pattern on to the mould, or on to the unprepared blocks that were to be carved into necks, scrolls, or marked out for ribs, would be Stradivari's. The different stages succeeding each other would be most likely as follows--firstly, the master having been commissioned by a wealthy patron to make of his best pattern and highest finish a quartet of instruments, he would take from his store of choice pine and sycamore, which he had taken so much trouble and skill in collecting together, such pieces that appeared to him suitable for the instruments to be constructed. The upper and lower tables had previously been hewn or sawn to size, then the jointed back and front, if both were so, planed carefully and made ready for the master's work, which would first come on to the wood as a careful tracing from his original design. Sometimes the tracing down may have been done by some advanced pupil or competent assistant. We may fairly assume the presence here of one or two, if not more, assistants, besides a pupil or improver. One would be selected for the bow-sawing of the pattern, another afterwards receiving it for roughly gouging out according to measurements at hand or marked by the master. Another had meanwhile the bending of the thin slips for the ribs to the necessary curves, or working down the corner and end blocks that had been affixed to the mould. Another, if not the same, might have been carrying out the first stages of the working of the scroll, or perhaps a very competent and trusty assistant would be allowed, under the eye of the master, to work on more advanced forms, making ready for the final or necessary touches of the master hand. The sound holes may have been traced down and even the upper and lower circular holes bored. Further, it is not impossible, that after the modelling back and front had been
