The substitution command should have yielded this result:

usverhulstfit = usverhulstfit/.%
Best Verhulst Model

Let's now plot a graph of this new model and see if we're happier with how it fits the data than before. Issue this command:

usverhulstfitplot = Plot[usverhulstfit, {t, 1790, 2010}, PlotStyle -> Brown]

Let's move on and see what you should have gotten...
