What is one massive project that theodore Roosevelt took on and built during his presidency

with my recent question

we pointed them north: recollections of a cowpuncher by e.c. “teddy blue” abbott tells us of the history of nomad cowboys in north america. as the   frontiers began moving west, trails of cowboys of the 1870s and ’80s drove herds of cattle from texas to the northern ranges and railheads, and then rode back south to do it again. they gradually pushed   native americans out of their lands, until in 1889 the   government transferred white   colonists the indian land.

how they should count slave votes (three-fifths compromise), the state representation in congress, and how much power should be given to our national government.
