Inthe construction ofthe masts of the Bel-lerophon and othersof the later iron-clads the arraugements have been similar to thoseshown in Fig. 207. The cross-stays are formed o^T-iron, and areplaced at intervals of about 6 feet throughout the masts. Thismode of forming and stiffening masts may be taken as the illustra-tion of the practice of Service, and as an example of thedimensions of plates, and stiffeners which are employed, we havegiven the following particulars of the masts of the fore-mast is
