Hittin' some yard sales

Well, actually, an estate/moving sale and a garage sale, but anyway. It was my exercise for the day, a mile and a half (I was surprised it wasn't more - but then it was very hilly). I scored 7 Cherry Ames books (sans dust covers, and there are two of one title - that'll teach me to read the titles before scooping them up!), a tiny bird book that's lost its cover, so I'll have some fun re-covering it, a box cheese grater, and a brand-new 6" x 6" sketch book. That ate up my $10 cash. Walking to sales is a really good idea - not only is it good exercise, it keeps me from buying a lot of things, or any big things.

Still chilly here - 45° - but sunny and breezy. I heard my first cardinal of the year, but could NOT find the bugger even though there aren't any leaves on the trees yet. He was laughing at me, I'm sure.

At one curb I noticed what seemed to be an over-abundance of official markings: the concrete curb itself had been embossed with the contractor's name; there was a "this drain leads to river" disk, and right next to it was a manhole cover over a storm sewer access shaft. The cover was iron, with the Seal of Omaha:

I stood and stared at this for several minutes, trying to figure out what all the various images mean. But it's the one in the center that baffles me. It seems like it *should* be a buffalo head, but what's that object running down the middle of it? In white in this image - stamped in iron it just looks like a blob. Could be a not-quite-stuffed bag of wheat, maybe? I can't figure it out. Yay, city symbols!
