Title: A note on the construction of Hamiltonian trajectories along
heteroclinic chains  

Abstract: 

We provide a short, simple proof of the existence
of Hamiltonian trajectories arbitrarily close to a given 
chain of heteroclinic orbits connecting ``codimension-one, 
KAM, whiskered tori".  

Keywords: Arnold diffusion, heteroclinic chains, KAM
