My dear Sir, I think that nothing of yours has ever escaped my reading 

 or failed to reward it; so I am very glad that you have consented to prepare

His book on "Domesticated Animals," illustrated by Seton 

 Thompson, called forth many enthusiastic letters from people 

 having pets and pet theories, who overwhelmed him with anec-

 our woods and waters. His reports on Swamp Lands, and the 

 Origin and Nature of Soils, prepared for the United States 

 Geological Survey, are among the most notable papers bearing
