  A survey of the northern hemisphere for astrophysical point sources with
continuous emission of high-energy cosmic rays is presented. Around 47 Mio
extensive air showers with primary energies above $\approx$ 300 TeV measured by
the KASCADE detector field are selected for this analysis. Besides the sky
survey, a search for signal excess in the region of the galactic plane and of
selected point source candidates has been performed. There is no evidence for
any significant excess. This is valid for an analysis of all recorded showers
as well as for a data set enhanced in gamma-ray induced showers. An upper flux
limit of around $3\times 10^{-10}$ m$^{-2}$s$^{-1}$ for a steady point source
that transits the zenith is obtained. Additionally, the distribution of the
arrival directions of extensive air showers with energies above 80 PeV were
studied by an autocorrelation analysis.
