Mr.Smith,who traches bloodhounds,give them a numberof lessons.
For the first lesson,he rubs liver on the hands of several boys.
Then he tells them to stand in line and hold their hands behind their backs.
He puts a small jar of liver in the pocket of one of the boys, and lets the young dog smell something belonging to this boy.
Then the dog must find this boy.If he goes up to the line of boys and picks out the wrong boy,
Mr.Smith hits him gently on the nose, but if picks out the right boy,he gets the jar of liver.
