:728 Doughty. An Essay on the Adaptation of [November,serts, that " the cold current is a comparatively narrow massat the point of its rising on the coast, and evidently is not feltnorth of the forty-fifth parallel." (See page 118.)These quotations are sufficient to show,, that this writer wasunable to designate the precise point at which the northernedge of this current impinged against the continent,nor indeedto indicate the exact direction of its northern boundary towardsthe place of its origin. To say the least, they were not wellappreciated by him, for some of his remarks are somewhat contradictoryof each other on these points. To this, however, wewould attach no censure, for the generalized facts of climate assought to be developed in the scope of his work, required onlythe knowledge of the existence, and the demonstration of somesuch controllingrefrigerating agent, without regard to any definitesize, and treated of it only in its relation to the entire continent.Hence there was no need of greater specification, thanhas been given to it.Now with a view of attempting to fix the northernmost pointat which this current touches the coast, amidst the obscuritywith which it is surrounded, we propose to ascend the coastfrom San Francisco, and observe the distribution of heat, withits differences of degree, at such places as have it recorded. Itmust not be forgotten, however, that it is not necessary, thatdirect contact of the cold waters with the shore shouldbe had,in order to refrigerate, or to reduce the mean of its temperaturedistribution.For, simple proximity, with a general atmosphericalcirculation, and other contributing local peculiarities, asheated plateaus, valleys, etc., may produce such a degree of refrigerationas is scarcely transcended by an immediate contactFor example, if we suppose the northern limit of this current,to be in a direction due southeast from the peninsular point ofAlaska, and to impinge against the western coast at the fortiethparallel of latitude, we would not expect its influence uponthat coast, to be limited to that south of the point of contact, buton the contrary,would look for it many degrees farther northward.Moreover, the direction of the winds which blow overand about that mass, would deeply affect the result, since theymust inevitably carry away with them the attendant cold surfaceatmosphere. An analogous instance has already been
Aug.Oct.1859.] Climate to the Consumptive, &c. 729mentioned in this paper, in the character ofthe atmosphere inducedby the prevalence of easterly winds along the Atlanticcoast for a few days, during which the air is rendered"sultry,oppressive, and heavy," by a transfer of these conditions fromthe Gulf Stream.The firstpost that we meet in the ascent of this coast, is FortHumboldt, lat. i0°.-i6 / ,near Humboldt Bay, California, andeastward two miles from the sea." The locality is a plateau ofslight elevation, fronting the Ba}*, and fully open to the Pacific."About a hundred miles interior to this, is Fort Jones, lat. 41°.36^, having a location " not closely confined, though with highmountains on the south and east."* The first has an altitude offifty feet, and the second an altitude of two thousand five hundredand seventy feet. The next station is Fort Orford, in Oregon,lat 42°.4r±', situated upon a bay with a direct exposure tothe ocean.The last that we shall introduce to the notice of the reader, isFort Astoria, lat. 46°.
