[ American Turf Registry and Sporting Magazine ]
This sporting monthly, with a primary emphasis on horse racing, was edited by J. S. Skinner and published (in Baltimore, Maryland) from 1829 to 1844.
The November, 1838, issue included an article on "Field Shooting in Virgina" that echoes a claim made by a number of other sporting writers in the 19th Century:
We never heard what character of dogs the cross of the pointer and Newfoundland would make. The latter is the most sagacious of the canine species, and his olfactory powers are exceeded by none. If his sagacity and nose could be engrafied upon the agility of the pointer, we should have all the essentials of a good dog. (509)
