they had learned to distinguish and obey with 
great accuracy and precision. The sight of two 
dogs charging promptly together, eying each 
other jealously, “hieing on” and “coming in” to 
order, is one that would elicit the admiration of 
the most indifferent spectator. When a child is 
made to recite the first lessons in addition which 
he has committed to memory,— for instance, one 
and one are two, one and two are three, and so 
on, —how readily he answers, and smilingly re- 
joices over his accomplishment; but pray observe 
his astonishment and confusion when the question 
is put to him out of the order as given in his 
book, or as he has been taught. The exercise is 
not unlike the one I have just recommended for 
the canine pupil, and there is none which serves 
to rivet the attention more firmly, or assists him 
more to distinguish, as I said before, the signifi- 
cance of the various commands without mistaking 
one for another. When your dog is perfectly 
familiar with the preceding lessons, he should be 
practised in varions ways and on different 
grounds, where the terms, the meaning of which 
has been taught him, are applicable.
