86 white men. This leads to the impres- sion that one white seaman is equal to two Chinese. This is not correct, as in every department of ship life, the Chinaman when once _ initiated into the white man's ways and speed, can perform equal work within equal time with him. Many stories have been written, many cases reported, of mutiny and insurrection of Chinese seamen against their white officers. The stories have all been told by the THE MARINE REVIEW suffering white officers, but they didn't tell of the long weeks and months of cruelty meted out by the "Scotch and soda" maddened 'tyrant upon the uncomplaining Asiatic. Even the worm will turn, and. the Chinese seaman will stand nearly as much as the worm before he turns. But if, when he turns upon his per- secutor, and vents the pent-up feel- ings produced by a long voyage of cruelty in savage atrocity, the blame of the whole thing still lies on the RR Ey Ms SOO BE March, 19] head of the white man. Their patience under trial, their perseverence to finish a job once started, their faithfulness to their superior officer when treated decently by him, their ability to withstand ex. tremes of cold and heat without com- plaining, their freedom from the curse of drink 'that unfortunately js the undoing of seamen of all other countries, makes the Mongolian aq model and valuable man oz ship- board. f Isherwood System of Construction "HELL EXPANSION.--The plan S herewith shows the shell plating expanded for the starboard side of the vessel. All the heavy lines excepting fenders show sight edges of the plating and the dotted lines show the interior stiffening; trans- verses vertically and the longitudinals lengthwise. Line of Tank at Side The double dotted lines running along from the stem to No. 20 trans- verse on H strake, dropping down to G strake at No. 20 and continuing aft on G strake to transverse No. 25, where it takes a drop to the seam of B strake at No. 29, the end of the water bottom aft, is the line of tank at side. This will be seen by refer- ence to the midship section shown in the first article. The keel strake is lettered A and runs from b to the stern post and is riveted to it. This strake is outside and in one width, the port and starboard bottom trans- verses being riveted to it. The keel plate is 36 in. wide, being 18 in. on each side. The center keelson angles are 4 in. wide and the center keelson plate 3/8 in.» thick, which makes @ fat patton the keel of 83/8. in. In this vessel a line 5 in. on each side of the vessel from the center ig. the stern post and like the keel plate run in and continued from No. 1 to the end of shoe aft, and forward of No, 1 gradually tapered down to 2% in. at the 2-ft. water line. This line forms the 'base of the expansion plan This is the seventh of a series of articles on the Isherwood System of Construction which began in the September Marine Review. The first article dealt with the general speci- fications of the steamer; the second with the sheer, half-breadth and body plans; the third explains the method of getting the sheer; the a ae ie peneiosdinal and trans- yerse framing; e fifth with offset sixth with the shell plating, ane Me In Which the Author Deals With the Shell Plating Expansion and the plating measured around the transverses is set up from this line, which gives the shape of plan. The keel plate strake after taking off 5 in. will leave 13 in. to be drawn par- allel to the base line: from No. 1 to 31. There are eight plates forming the keel strake. The first one No. 1 is 25 Ibs. per square foot and the balance 272 Ibs: The weight of the plate may be confusing to some, but if it is remem- bered that 1% in. is equal to 5 lbs. the thickness of the plating can be real- ized. The keel plate No. 1 is 5/8 in. thick. The two after plates on the keel strake when shaped at the furnace will be like a box with the top and ends off. Owing to the heating of these plates to shape them, they are thinner when finished, so that it is necessary to order them midship weight from the mill, to allow for the reduction in thickness, during process of shaping and when they are finished will prob- ably be the same thickness as No. 1. This strake is always made flush at the butts and strapped on the inside. Two Longitudinal Frames B strake is an inside. strake and runs parallel to the keel seam and base line from transverse No. 2 to is riveted to it. There are nine plates on this strake, the four after plates being reduced in thickness from 17.5 to 15,5 Tbs. There are two longitudinal frames on this strake of plating. C strake is an outside strake and runs parallel to B but does not run the whole length of the vessel; the lower edge runs from No. 2 to 29 and the upper edge from No. 4 to 26 \ transverses. There are seven plates on this strake, the two after plates be- ing reduced from 17.5 to 15.5 Ibs. per square foot. There is one longi- tudinal frame on this. strake of plating.. D strake is still shorter and practi- cally ends the straight of the bottom plating. This strake is inside and the lower edge runs parallel to the base line from No. 4 to 26, the upper edge being shaped to suit the lower edge of the lower bilge strake E. There are six plates on this strake, the after one being reduced in thick- ness. There are two longitudinals on this strake of plating. The Tank Side E strake runs from the stem to the stern post and is riveted to: both. The top edge follows the sheer while the bottom edge is parallel to the base line from No. 8 to 21° transverses. This is an outside strake and has nine plates on it, the after one No. 9 covers the boss and for the same reason as. the two after keel plates No. 9 is the same thickness as the midship. plating; Nos. 6, 7 and 8 are reduced to 16 lbs. The tank side crosses this strake from No. 25 to 29 and all the close spacing of transverses end at this line, the transverses above the tank being 12 ft. apart. There are two longitudinal frames on this strake of plating which tun from the fore peak bulkhead to the after peak. " G strake is an inside strake which runs from the stem to the stern post and forms the upper part of the bilge. There are ten plates on this strake, the four after ones being reduced in thickness. There is one longitudinal frame on this strake and the tank side runs across it from No, 20 to 29.
