Thanks for accounts which make everything intelligible to him. Since he was glad to have Orchids published at one-half of profits for himself, he believes it would be very shabby to accept JM’s new offer of two-thirds profits. Thinks it would be fairer to both to change to JM’s usual practice with authors [i.e., annual statements of sales, payments based on them, and final accounting when all copies have been sold].
