Dear friend,
In a very few days I shall write to you at length, and at the same time explain to you why this letter is so short. For the present only this, because it must not be delayed: Royalties, nothing else. If these royalties are to be lucrative—i.e., if my operas are to be given frequently—the manager must be well and sincerely inclined to the cause. Therefore we will treat him nobly. You have written most excellently.
In a few days more from your R. W.
