the meridian of Winter Harbour to the entrance of Sir James 

 Lancaster's Sound, a distance which it required five weeks to 

 traverse when going in the opposite direction, seems to offer a 

 reasonable ground for concluding, that an attempt to effect the 

 north-west passage might be made with a better chance of suc- 

 cess, from Behring's Strait, than from this side of America. There 

 are some circumstances, however, which, in my o])ini()n, render 

 this mode of proceeding altogether impracticable, at least for 

 British ships. The principal of these arises from the length of 

 the voyage which must first be performed, in order to arrive at 

 the point where the work is to be begun. After such a voyage, 

 admitting that no serious wear and tear have been experienced, 

 the most important part of a ship's resources, namely, the pro- 

 visions and fuel, must be very materially reduced, and this with- 

 out the possibility of renewing them, to the extent necessary for 

 such a service, and which can alone give confidence in the per- 

 formance of an enterprise of which the nature is so precarious 

 and uncertain. 



' Nor should it be forgotten how injurious to the health of the 

 crews, so sudden and extreme a change of climate would in all 

 probability prove, as that which they must necessarily experience 

 in going at once from the heat of the torrid zone into the intense 

 cold of a long winter upon the northern shores of America. Upon 

 the whole, therefore, I cannot but consider, that any expedition, 

 equipped by Great Britain with this view, will act with greater ad- 

 vantage, by at once employing its best energies in the attempt to 

 penetrate from the eastern coast of America, along its northern 

 shore.' 



The embellishments consist of maps, charts, and other en- 

 gravings, to the number of twenty in all, and are, generally speak- 

 ing, highly appropriate.
