Answer:
The quote "Applying Peruvian guano" by Charles Bartlett in 1860 reflects a feature of economic imperialism by the United States, namely the United States expanding its territorial possessions to secure commodities for the domestic market. Peruvian guano was a highly valued fertilizer in the 19th century, and the United States sought to secure a steady supply of it to support its rapidly expanding agricultural sector. The United States became the largest importer of Peruvian guano, and the demand for this fertilizer was so high that Peru became heavily dependent on its export.
The United States sought to secure its access to Peruvian guano by pursuing policies of economic imperialism. This involved expanding its territorial possessions in the Pacific and Latin America, and using military force and diplomacy to influence foreign leaders to support American economic interests. The U.S. government also offered financial and political support to American companies operating in foreign markets.
Overall, the pursuit of economic imperialism by the United States reflected its desire to secure access to key resources for its domestic market, and to promote the interests of American businesses operating in foreign markets. This had a profound impact on the development of the global economy, and shaped the political and economic relationships between countries around the world.
