Oceanography. 46 DEPTHS OF THE OCEAN " Michael Sars " tow- nets for hori- zontal and vertical ance to the water, both while being lowered and hauled in. It is, besides, quite use- less for towing, for which purpose it was never intended. In the construction of our nets on the "Michael Sars" our idea was to make the fore part in such a way that as much water as possible might percolate through. As a rule they are i metre in diameter at the entrance and metres long (see Fig. 29). The fore part is cylindrical for a length of 1^ metres and of the same size as the entrance. There is first half a metre of shrimp net, then 1 metre of coarse silk with a mesh of mm., and the after part, consisting of a cone, 3 metres long, of finer silk with a mesh of mm. These filter the water admirably. We can tow them at a great speed and haul them on board rapidly, even with the little after star- board winch; and Fig. «Michael Sars' they Capture young Ai net; B, coarse silk; C, finer silk.
