marred by adding something of his own. It is quite obvious that
what he adds comes from genuine and original talent, from his own
musical individuality; but he is not master of himself; he has no
style; he is an untrained musician. If he be a diamond, he is
certainly in the rough and unpolished."

Ole Bull sought out the writer of this criticism, who gave him valuable
advice, and for six months he devoted himself to ardent study under the
guidance of able masters. In this way he learned to know himself, the
nature and limitations of his own talent.

We now arrive at the point in Ole Bull's career at which he became
celebrated, and this was due to accident. He was at Bologna, where De
Bériot and Malibran were to appear at one of the Philharmonic concerts.
By chance Malibran heard that De Bériot was to receive a smaller sum
than that which had been agreed upon for her services, and in a moment
of pique she sent word that she was unable to appear on account of
indisposition. De Bériot also declared himself to be suffering from a
sprained thumb.

It happened that Madame Colbran (Rossini's first wife) had one day heard
Ole Bull practising as she passed his window, and now she remembered the
fact, and advised the Marquis Zampieri, who was the director of the
concerts, to hunt up the young violinist. Accordingly, Ole Bull, who had
gone to bed very early, was roused by a tap on the door, and invited to
improvise on the spot for Zampieri. Bull was then hurried off, without
even time to dress himself suitably for the occasion, and placed before
a most distinguished audience, which contained the Duke of Tuscany and
other celebrities, besides De Bériot, with his arm in a sling.
