The bald eagle is the national bird of the United States and has been a symbol of the country since 1782.
The bald eagle represents the United States and its growing imperial ambitions at the turn of the 20th century.
The cartoon is criticizing the United States' annexation of the Philippines in 1898, which was seen by many as an imperialist act. The eagle is shown stretching its wings over the Philippines, suggesting that the United States is trying to expand its control over the islands.
The caption of the cartoon, "Ten thousand miles from tip to tip," also highlights the growing size and power of the United States. In 1798, the United States was a much smaller country, but by 1898, it had expanded its territory from the Atlantic to the Pacific Ocean.
