Saddle-to-bar drop/rise is simply the difference in height (from the floor) between the saddle and the bar. Looking at your Jamis in your gallery, it looks like you have the stem at almost the same height as the saddle, but on the Trek, there appears to be more drop.

That said, looking at the two bikes overall, the sloping top tube can trick the eye, but still, the Jamis does appear to be a bit bigger frame.

Edit - yes, you got the saddle-to-bar thing right. Doesn't look like 2" difference from the photos, but the tame measure doesn't lie. Also, if you're comparing riding positions on the hoods, the brakes are lower on the bar on the Trek. At the risk of proposing blasphemy, if you're used to a more modern position on the hoods with the brake levers more "integrated" with the bar, a new-ish set of Tektro levers, and possibly a newer-style bar to match, might help with that positioning.
