<p>Political Cartoon on Canadian-American relations from 1886. Canada explains to Britannia that she has no desire for union with the United States. 
</p>
<dl><dd>Mrs. Britannia.—“Is it possible, my dear, that you have ever given your cousin Jonathan any encouragement?”</dd>
<dd>Miss Canada.—“Encouragement! Certainly not, Mamma. I have told him that we can <i>never</i> be united.”</dd></dl>
Note that the depiction of the United States largely matched what was becoming the standard "Uncle Sam" personification, but is referred to by the older name (Brother) Jonathan.
