We have mapped in neutral hydrogen (HI) two regions at the northern tip ofthe Magellanic Stream, known as MS V and MS VI, using the Arecibo telescope.The small-scale structure of the MS shows clumpy and head-tail morphology. Thespatial power spectrum of this star-free intergalactic medium has a power-lawbehavior with the density slope of -3.8. A gradual steepening of the power-lawslope is seen when increasing the thickness of velocity slices.Comment: 2 pages, 1 figure. To appear in the Proceedings of the Meeting on Gaseous Matter in Galactic and Intergalactic Space, XVIIth IAP Colloquium, Paris, June 200
