[R] no labels when plotting dendrograms

I'd like to be able to cut dendrograms at a height I specify
and then plot the resulting subtrees. I wanted to use the
dendrogram object for this purpose because there doesn't seem
to be a canned way to cut a hclust object and get a list of
hclust objects, but there is a function (cut) that does that
for dendrograms. The problem I'm having is that when I plot
a dendrogram, I can't figure out how to add labels to the nodes.
For example, this example from the dendrogram documentation
plots a dendrogram without labels:
hc <- hclust(dist(USArrests), "ave")
str(dend1 <- as.dendrogram(hc))
dend2 <- cut(dend1, h=70)
So... does anyone know how to cut an hclust object and get a
list of hclust objects, or how to plot a dendrogram object with
