  We present three bijections, the first between little Schr\"{o}der paths and
a class of growth-constrained integer sequences, the second between lattice
paths consisting of steps with nonnegative slope and another class of
growth-constrained sequences, the third between a class of lattice paths with
steps $(1,1)$ and $(1,-j\,),\ j\ge 1$, and a class with steps $(k,1),\ k\ge 1$,
and $(1,-1)$.
