Hours they practised until far in the night, and when Malcolm felt he really had located a bird, gained its attention, and set it singing against him, he was wild, and nothing would satisfy him but that his father should go to the swamp with him, and well hidden, hear and see that he called the bird. Gladly Mr. Minturn assented. Whether the boy succeeded in this was a matter of great importance to his father, but it was not paramount. The thing that concerned him most was that Malcolm's interest in what he was doing, his joy in the study he was making, had bred a deep regard in his heart for his instructor. The boy loved the man intensely in a few days, and immediately began studying with him, watching him, copying him. He moved with swift alertness, spoke with care to select the best word, and was fast becoming punctiliously polite. On their return Mr. Dovesky had fallen into the habit of lunching with the Minturns. The things of which he and the boy reminded each other, the notes they reproduced by whistling, calling, or a combination, the execution of these on the violin, the references Mr. Dovesky made to certain bird songs which recalled to his mind passages in operas, in secular and sacred productions, his rendition of the wild music, and then the human notes, his comparison of the two, and his remarks on different composers, his mastery of the violin, and his ability to play long passages preceding and following the parts taken from the birds, were intensely absorbing and educative to all of them. Then Mr. Tower would add the description and history of each bird in question. Mr. Minturn started the boys' library with interesting works on ornithology, everything that had been written concerning strains in bird and human music; the lives and characters of the musicians in whose work the bird passages appeared, or who used melodies so like the birds it made the fact apparent the feathered folk had inspired them. This led to minute examination of the lives of the composers, in an effort to discover which of them were country born and had worked in haunts where birds might be heard. The differing branches of information opened up seemed endless. The change this work made in the boys appeared to James Minturn and his sister as something marvellous. That the work was also making a change in the heart of the man himself, was an equal miracle he did not realize.
