Who wrote the lines of poetry "quoted" by Lincoln at the Soldiers' Home?

Roger,

The Winds of Change: A Novel about the Last 14 Months of the American Civil War
By Richard Guida pg139 (Screenshot of pg in 1st attachment).

Note the author has Lincoln using the 4 lines in a different place. I wonder whether Lincoln may have made his own poem while utilizing the first two lines of the Collins ode. It was not unheard of. The 2nd attachment is another poem that utilizes the lines from the Collins ode. It was taken from the Los Angeles Times, 30 May 1892, Mon, Pg10.

When Lincoln recited for the ladies at the cemetery why didn't he quote the original ode in its entirety? Could it be he had a unique version he preferred, from his own poetry. The 2 halves do fit together nicely, in a shorter version.
