Directly across the road from the Lincoln Boyhood National Monument in the aptly named Lincoln City, Indiana is Lincoln State Park. I paid the $9 out of state entrance fee and went to visit with Sarah Lincoln, Abraham’s sister.
Sarah was born two years and two days before Abraham. Their younger sibling, Thomas Jr., died a few days after his birth, so Abraham always looked up to and cherished his older sister, especially after their mother died and Sarah became for a time the woman of the family at age eleven. Sarah married Aaron Grigsby when she was eighteen, but died during childbirth a year and half later.
So my visit was to see Sarah’s grave. Winding through the wood-lined roads of the State Park I found the Little Pigeon Primitive Baptist Church where the family attended services. Abraham served as church sexton, responsible for maintaining the church property, ringing the bell for services, and digging graves. Behind the church is Old Pigeon Cemetery, which holds the final resting place for many of the first families of the Little Pigeon Creek settlement. Sarah’s gravestone was one of the first in the cemetery, and one of the most prominent. It’s certainly one of the cleanest, maintained pristine for Lincoln pilgrims, who often leave pennies – featuring Abraham Lincoln’s profile – on the relief flower bough that adorns the center of the stone.
Her husband Aaron Grigsby’s gravestone is there too. In contrast to Sarah’s, Aaron’s stone is a small obelisk darkened by age and lack of maintenance. I suppose the reflects their relative positions in American history.
On my way out of the park I stopped at an area I had spied on the way in listed rather unhelpfully as the “Abraham Lincoln Bicentennial Plaza.” The plaza was dedicated in 2009, the bicentennial of Lincoln’s birth. From the parking lot all you can see is trees, but as you follow the short path you suddenly find yourself viewing a small plaza with a semi-circular stone monument. With help from the ample signage, you realize that the roughened portions of the stone in front of you represents Abraham’s height for each of the fourteen formative years he lived in Indiana.
Around the back is another surprise. What seems like a circular monument on one side turns out to be only half a circle. The back side features a half statue of Lincoln in front of a wall engraved with the Gettysburg Address and the proration from his Second Inaugural Speech. On the statue’s base, the sculptor, Will Clark, explains the positioning of the hands:
Lincoln’s closed left hand symbolizes his desire to hold the Union together, and his open right hand symbolizes his desire for a strong, positive, post-war reconciliation with the South.
There is more to see in Lincoln State Park, including a Lincoln amphitheater and other areas related to Lincoln. After the park, I headed north. Tomorrow would be a research day in the library. More on that next. Meanwhile, for more on my Chasing Abraham Lincoln travels, follow the link and scroll down.

From here there is a short walk up a landscaped tree-line allee to the gravesite of Nancy Hanks Lincoln designed by Frederick Law Olmstead, Jr. Lincoln’s mother had died in 1818 of what was called “milk sickness,” later to be associated with cows eating the toxic white snakeroot plant. Her grave remained unmarked until a permanent marker was erected in 1879.

In the last quarter of my most recent 2000 mile road trip we met a lovely couple at a Montana rest stop. Gene and Jacque were sitting in foldable chairs next to their large RV camper when we pulled in to stretch our legs. As we talked about life I realized that very day – September 12th – was the 5-year anniversary of my science traveling life.

Tesla had begun working on bladeless turbines when he was consulting with the Westinghouse Company in Pittsburgh, but this project, like so many others, was put on hold while he toiled on his alternating current designs of high potential and high frequency. But in 1906 he gave himself a fiftieth birthday present by demonstrating his bladeless turbine in public. The basic design of the turbine relies on the principle of boundary layer flow, that is, where the movement of the liquid or gas passes over a series of smooth disks. Some of the liquid or gas adheres to the disks, which creates a vortex that spirals toward the center and spins the turbine. Tesla described it in an interview with the New York Herald in 1911:
Yesterday I visited the Portrait Gallery in Washington, D.C. The Gallery shares a building (once the Patent Office) with the Smithsonian American Art Museum but because it sits several blocks off the National Mall it is often overlooked by tourists and locals alike. That’s a shame because the two museums house some of the most important and relevant art to our times.
It is with deep regret that I mark the sudden passing of John Elliff. John was an Abraham Lincoln scholar and in many ways my mentor in the Lincoln field.
