The transport of cosmic rays in the interstellar medium is reviewed with emphasis on interactions with the turbulent interstellar magnetic field. It is shown that the standard picture of cosmic-ray transport suggests strongly the existence of a smooth turbulence spectrum of the range of scales between 10/sup 12/ and 10/sup 19/ cm. This, coupled with observations of radio wave scattering and other direct measurements suggests a smooth, power-law turbulence spectrum over the range of scales from 10/sup 9/ to 10/sup 19/ cm, with the index of the power law being close to that of the Kolomogorov equilibrium subrange. Attributing this to a turbulent cascade leads to severe difficulties. Suggestions for avoiding these difficulties are discussed.
