Spectators,--myriad numbered, greeting with enthusiastic plaudits, the departure of stately fleets, that at intervals during successive centuries, have passed out, destined to carry the grand conquests of the seamanship and valour of the English race,--triumphs martial and commercial,--to every sea; or anon, sorrowful groups with down-cast hearts, wafting sad and final farewells to those, who have here in continuous exodus set out to seek new homes on distant shores, and from hence cast their last "longing, lingering look," at the receding, vanishing outline of their native land; or again, eager eyes anxious to descry the first rise of the sail of the home-bound ship on the distant horizon, bearing a freight more precious to the love-strained heart, than all the wealth of Ind. But while these suggestive thoughts are haunting us, we have slowly crept up to the warlike precincts of the lower Hamoaze. We pass the huge, cavernous, pent-house-looking, but now empty 'slips,' hanging over the darkling tide, in which the 'wooden walls' of _old_ England were wont aforetime to be built, ere the steam-urged iron monsters of our present _new_ England were dreamt of. And we ruminate a moment over this change of times and things, and mentally ask the question, What is the gain to human development achieved by much of the scientific--_ergo_ mechanical--appliances of the present hour? the which, while it flatters the lord of creation with the belief he has become the autocrat of the forces and elements, in truth practically reduces that proud being to be the servant and care-taker of the machine he has constructed, for assuredly to a very large extent to this menial occupation he is being rapidly reduced. Specially with regard to ships and navigation, a generation or two ago, vessels in construction and appearance were not only beautiful objects as such, but required also all the skill, foresight, courage, and dexterity which taxes the resources of manhood to the utmost, and forms the basis of true seamanship, for their guidance and control. Then there was something both for the mind and bodily energy alike to exercise and develope itself on; and undoubtedly much of the secret of our victories, both in commerce and war, that we have achieved in the past, may be traced to our proficiency therein, and as a consequence, the cause of our winning the crown of success among all other competing maritime nations.
