clouds and move together through space, away from
their birthplace. They cohere or hang together as long
as possible in defiance of the galactic tidal waves, yet
suffer loss of star after star until all are dispersed in
an endless trail across the galactic plane. The speed
of "evaporation" of the cluster stars depends greatly
on their density in the cluster. A dense, compact
cluster will be much more stable than a cluster of low
density. The Hyades cluster is perhaps safe for about
a thousand million years, whereas the Pleiades and
Praesepe may endure for ten times that period.
