Collation of the magnetic fluctuations (D, H and Z separately) at the magnetic hut and at the inland observation-point (10 km from the hut) yielded the following results: (1) The D, H and Z fluctuations inland and at the magnetic hut were identical in character, but the Z curve at the inland point is somewhat smoothed; (2) the amplitudes of the H fluctuations at the inland point were for the most part larger than at the hut, with differences amounting to 0 - 50% of the size of the fluctuations. But often (in 25% of all collated cases) the amplitudes at the inland point were smaller than at the hut by 0 - 20%; (3) likewise the amplitudes of the D fluctuations at the inland point were for the most part larger than at the hut by as much as 20%, but often, as in the case of the H amplitudes, the opposite relationship was observed; and (4) the amplitudes of the Z fluctuations on the continent were in the overwhelming majority of cases (36 cases out of 40) larger by 10 - 60% than at the hut.
