NAVAL ARCHITECTUR E— S TEAM VESSELS. 



We have, at very considerable trouble, formed a complete Table of proportions of the whole of the timbers, with but few exceptions, used 

 in the construction of Timber-built Steam Vessels. We believe that this table is the first of the kind that has appeared in print, and doubtless 

 it will, we hope, prove a valuable acquisition to all parties connected with steam navigation, and become a model for forming similar tables of 

 other vessels. 



The "Royal Tar" and "Don Juan" were built for the Peninsular packet service; the first vessel is now on duty, and running between 

 Southampton and Gibraltar, the other vessel was lost. The specification of the West India Mail Packets is very deficient ; we understand that 

 those built for this service by ditFerent builders vary in their proportions, excepting such parts as are described in the table.
