The Atrato River, which rises in the foot 
hills of the Andes and empties into the Gulf 
of Darien, an arm of the Caribbean Sea and 
which England threatened to make into a 
canal connecting the two oceans if not given

navigable for about 225 of its 350 miles. The 
largest river on the Pacific side is the San 
Juan, being navigable for 150 of its 200 or 
more miles. The rivers emptying into the 
Amazon are navigable for canoes and lighters, 
but are so remote and in such a sparsely popu 
lated region as to be negligible quantities in 
this connection. 
Agricultural experts estimate that only one- 
third of Colombia is susceptible of cultiva 
tion, the eastern part being swampy and the 
high mountain lands incapable of sustaining 
any growth, especially at an elevation of 
13,000 feet. The belt of coast lands with the 
plateau regions can be made highly produc

Coffee is perhaps the largest crop grown, in 
1913 the output being nearly 53,993 tons val
