  We report on our recent progress in the manipulation and cooling of a
magnetically guided, high flux beam of $^{87}{\rm Rb}$ atoms. Typically
$7\times 10^9$ atoms per second propagate in a magnetic guide providing a
transverse gradient of 800 G/cm, with a temperature $\sim550$ $\mu$K, at an
initial velocity of 90 cm/s. The atoms are subsequently slowed down to $\sim
60$ cm/s using an upward slope. The relatively high collision rate (5 s$^{-1}$)
allows us to start forced evaporative cooling of the beam, leading to a
reduction of the beam temperature by a factor of ~4, and a ten-fold increase of
the on-axis phase-space density.
