  We investigate the mapping class group of an orientable $\omega$-bounded
surface. Such a surface splits, by Nyikos's Bagpipe Theorem, into a union of a
bag (a compact surface with boundary) and finitely many long pipes. The
subgroup consisting of classes of homeomorphisms fixing the boundary of the bag
is a normal subgroup and is a homomorphic image of the product of mapping class
groups of the bag and the pipes.
