Heavy rain for a while today and cooler temps, but not till afternoon, so there was time for one more lunch on my deck.

Ann invited us to visit her over the weekend, which we did, heading down to Normal on Saturday morning and returning Sunday afternoon, spending the night in a motel near I-55. Daytime temps were nearly as warm as when I dropped her off at ISU in August.

Toward the end of the day on Saturday, it had cooled enough for a short walk — including the dog, whom we brought — around the prettier parts of campus. Mostly that meant the ISU Quad. What’s a university without a quad or two?

As mentioned yesterday, most of the foliage is still green. An eastern approach to the Quad.

“The Hand of Friendship,” which honors Robert G. Bone.

Bone (1906-1991) was the ninth president of Illinois State Normal University, which was renamed Illinois State University during his tenure. Though only president for 11 years (1956-67), he oversaw a lot of construction, including the tower where Ann lives. Later, the school’s student center was named after him.

The Quad also counts as the heart of the arboretum that spans the campus — the Fell Arboretum, to cite its formal name, honoring one Jesse Fell.

Fell (1808-87) was the sort of businessman that America spawned in the 19th-century — lawyer, real estate speculator, newspaper publisher and sawmill owner. Specific to Illinois, he was a friend of Lincoln’s. He founded towns in central Illinois and helped organize counties there as well, and is considered a founder of ISU.

As for the arboretum, apparently Fell not only profited from cutting down trees, but was a fanatic when it come to planting them, so ISU named it in his honor.

Elsewhere, we saw a plaque on a rock honoring the horticulturist who designed the original landscape for the campus, William Saunders (1822-1900), who also happened to be a founder of the National Grange of the Order of Patrons of Husbandry, an organization I had only scant knowledge of before. That is to say, little that I remember, though I’m sure heard about the Granger movement in a U.S. history class. Always good to learn or re-learn something.

In the middle of the Quad is a lush garden.

The centerpiece is the Old Main Bell, dating from 1880.

Old Main was the campus’ first building, which stood from 1857 to 1958. A memorial honors the building not far from its bell. Unusually, it depicts all four elevations of the building.

We wandered on. This is Cook Hall.

“One of Illinois State’s most interesting buildings and the oldest one still standing on the Quad, Cook Hall was originally built to be a gymnasium,” ISU tells me. “It was completed in 1897 and was named after John Williston Cook, the University’s 4th President (1890-1899). He earned his diploma in 1865 from Illinois State Normal University and in 1876 he became a Professor of Mathematics.

“The building has also been known as the ‘Old Castle’ or ‘The Gymnasium.’ The governor at the time, John Altgeld, had a great liking for medieval castles and insisted all new state construction during his term in office resemble castles. You’ll find a Cook Hall look-alike at many other state schools; they are called ‘Altgeld’s Folly.’ ”

Really? I had to look into that more, and found this Wiki item about Altgeld Castles. It does indeed seem that a raft of crenellated, or quasi-crenellated buildings at Illinois state schools dates from the 1890s. I remember seeing Altgeld Hall at UIUC, but didn’t know it was part of a pattern. An eccentric pattern. That’s two things I learned (or relearned) today; makes for a good Monday.
