fitted with Diesel motors of 360 H.P. More recently the “Emanuel
Nobel” and “Karl Hagelin” have been built for the same firm;
they are fitted with Diesel motors of 1200 H.P., are 380 ft. long,
46 ft. beam, 1612 ft. draught and carry 4600 tons of kerosene oil.
The large motor-driven vessels are arranged somewhat similarly to
the steam-driven oil-tank vessels, but with the machinery fitted in a
comparatively shorter space, no boiler room being then required.

Table X. gives the dimensions, carrying capacity and other leading particulars of four cargo steamers of different types, and one steamer carrying mails and passengers as well as a large cargo. A is a well-decked vessel (fig. 13, Plate II.), having a top-gallant forecastle with a long raised quarter-deck and bridge-house combined, and is fitted with one deck, but has two tiers of beams. B (fig. 14, Plate II.) is a vessel with a top-gallant forecastle, bridge-house and poop, and a single deck. C is an awning-decked vessel, with two decks, but three tiers of beams. D is a shelter-decked vessel of the highest class fitted with three decks and four tiers of beams and having machinery of high power. E is an American lake steamer in which the draught was limited to 20 ft., similar in many respects to the smaller vessels shown in fig. 15 (Plate II.) and in fig. 16 below.

Besides the principal dimensions and light and load displacements the block “coefficients” corresponding to the load conditions are given in Table IV., in order to show the fullness of form commonly adopted in these vessels.
The block coefficient is the ratio of the
