Dear Mr. Althaus,

I have read with interest your admirable book, "Advice to Pupils and Teachers of the Violin." I have no hesitation in recommending it as an indispensable work to all aspiring violinists and teachers. Your remarks on the acquirement of the various bowings, with the many musical examples, are excellent. I know of no work on this important subject so explicit and exhaustive. Wishing your book the great success it deserves,

Believe me, yours sincerely,
