Data obtained by mechanically vibrating a superconductor sample in a magnetic field indicate that the Abrikosov fluxoids penetrate the sample in jumps. The number of vortices entering the sample in each jump is so high that even if they were distributed over the entire sample surface prior to penetration they would fill several surface layers with total thickness on the order of the penetration depth, and so densely that the distance between them would be of the order of the coherence length. This suggests that a surface barrier of such an assembly of ''protovortices'' is small compared with the insurmountably high barrier for a single vortex.
