You likely can see the problem. If not, this is what the Washington Monument looked like in 1860:

To sum up quickly, the cornerstone was laid in 1848. Construction stopped in 1854 when the Know-Nothings[1] got all bent out of shape because the Pope donated a commemorative stone to the monument.[2] Construction didn't resume until 1879; the monument was finished in 1884 and dedicated in 1885, about two months before the 20th anniversary of Lincoln's assassination.

During Lincoln's presidency, the stump of the monument was what was there.
