No hat at all.
Though years later I'd look through the field next door for arrowheads and sometimes wore a leather hat with the brim snapped up on one side.
If I had to pick one... I guess I'd say cowboy hat.

Maybe i saw the same one...It was about roman cement.. apparantly natural cement.. (ie, heated crushed limestone) often ends up with a slighty pinkish tone. **edit: i suppose i should say that the limestone the romans used was a little pinkish. not sure if all limestone does this**
funny to think the roman buildings were often pink.

That was it, they also mixed it with volcanic ash allowing them to build massive buildings. It was not until the early 1800 that a cement that came close to matching theirs.

Wissahickon Schist
"a variety of schist named for the craggy valley of Wissahickon Creek where the stone was first studied. With its flecks of glittery mica and its many-toned shadings of gray, brown, tan, and blue, Wissahickon schist is so attractive that it became a common building material in the nineteenth and early twentieth centuries. "

It also frequenltly has garnets embedded all through it like mini chocolate chips.
The thing about this stuff that's so cool though, is that when quarried it is so soft you can cut it with a hand saw pretty easily. But once it is exposed to air, it rapidly hardens to a remarkably strong material.
Many of the houses in the area where I grew up were made of it, and it really is pretty stuff.
Here's another cool historical note from

Americans' attack at Germantown melts into panic
By Michael D. Schaffer
Inquirer Staff Writer
Sixth in a series of articles recounting Philadelphia's days in the Revolutionary War.
The grandest house in Germantown is under siege.
American soldiers fire volley after volley at Cliveden, the elegant Georgian summer home of Pennsylvania Chief Justice Benjamin Chew.
Six-pound American cannonballs slam against the house's 2-foot-thick front wall of Wissahickon schist, only to bounce harmlessly away.
More than 100 British soldiers have barricaded themselves inside the sturdy house and are frustrating all attempts to blast or burn them out. These Redcoats, from the 40th Regiment, have a special reason for not wanting to surrender: They may well be killed, because they were part of the British force that stabbed its way through Gen. Anthony Wayne's camp at Paoli two weeks ago in a fierce bayonet attack that Americans are calling a massacre."
Wish I could find you some nice color pictures. Nothing turning up easily on Google. Maybe I'll have more time to look later.

LOL! When I was a little girl, I wanted to be an oceanographer and a ballerina. Dancing around the bathysphere in toe shoes, I guess.
