  We present new measurements of heavy cosmic-ray nuclei at high energies per-
formed during the first flight of the balloon-borne cosmic-ray experiment CREAM
(Cosmic-Ray Energetics And Mass). This instrument uses multiple charge
detectors and a transition radiation detector to provide the first high
accuracy measurements of the relative abundances of elements from boron to
oxygen up to energies around 1 TeV/n. The data agree with previous measurements
at lower energies and show a relatively steep decline (~E$^-0.6$ to E$^-0.5$)
at high energies. They further show the source abundance of nitrogen relative
to oxygen is ~10% in the TeV/n region.
