730 Doughty. An Essay on the Adaptation of [November,at Fort Humboldt the sea influence does not indicate that intensityof operation, which was noticed at the former station ;forFort Jones, one hundred miles inthe interior, shows no appreciableeffect from this cause. In other words, it does not penetrateso far into the interiorState, but limits itself to the immediate coast.as in the more southern part of theIts mean temperaturesfor the summer months are much higher, than those ofeither of the preceding posts,and its mean summer temperatureis fully ten degrees (10°) greater. It presents in the course ofthe mean temperatures then, more of the ordinary manifestationsof interior localities of similar altitude.This confinementto the coast may be accounted for by reference to the absenceof the San Joaquin and Sacramento Valleys, with their furnaceliketemperature.Examining the next in the table, FortOrford, whose situationupon the immediate coast, and direct exposure to the ocean,makes it a true exponent of the measure of refrigeration at thislatitude, we remark an elevation of two and sixty two hundredthsdegrees, (2°. 62) per month for the summer season overSan Francisco ; and a monthly average of two and seventyhundredths degrees, (2°. 70) over Fort Humboldt. AddiDg Septemberto the three summer months, and taking the averageincrease per month, it stands two and thirteen hundredths degrees,(2°.13) over the first; and two and forty-nine hundredthsdegrees, (2°.49) over the second. Looking also at the meansummer temperatures, that of Fort Orford is two and sixtytwohundredths degrees, (2°.62) higher than that of San Fran_cisco ; and two and twenty-five hundredths degrees, (2°.25\higher than that of Fort Humboldt.The last post of the table, Fort Astoria, situated near themouth of the Columbia River, latitude 46 Q .11 / N., shows a stillhigher elevation of temperature over these two places, the meanmonthly increase over them for the summer months, being fourand twenty-eight hundredths degrees, (4°.28) over San Francisco;and four and thirty-six hundredths degrees, (4°.36) overFort Humboldt. Adding September to those months, we haveas the monthly average of increase for the four months, threeand eighteen hundredths degrees, (3°. 18) over San Francisco;and three and fifty-five hundredths degrees, (3°.55) over Fort

To this point, the refrigeratinginfluence appears to be about the same. Progressing1°.58 / farther northward to Fort Orford, Ave observe a suddenand material increase of 2°.70 per month, over Fort Humboldtfor the summer season ;and from June to September, anaverage monthly increase of 2°.49 ;also a higher mean summertemperature by 2°.2o. Then continuing 3°.27' farther up toAstoria, we have an elevation of 1°.66 per month, over FortOrford, for the summer ; and a monthly average of 1°.05, fromJune to September. Hence we see within a distance of twodegrees of latitude, a sudden elevation of temperature amountingto 2°. 70 per month for the summer. And within five anda-halfdegrees of latitude, a mean monthly elevation of 4°.36 forthe summer over Fort Humboldt, and a difference in the summermeans of 3°.88. To what may this difference of temperaturewithin so short a distance be attributed ?Now perhaps we are better able to locate the northern edgeof this cold current, and to appreciate the point near which itsdirect effects cease, and where those ofsimple proximity begin.Fort Humboldt certainly falls within the range of its region ofcontact, for the slight and mere nominal differences that existbetween it and places five or six degrees of latitude farther south,afford positive proof of the fact. That it extends any distanceabove this point, is exceedingly problematical, for an advanceof not quite two degrees of latitude, gives a much greater- differenceof temperature, than has been noted for at least six degreessouth from that point. And advancing five degrees from thispoint, such differences are observed as point to an almost entireabsence of its influences, direct or indirect. It is likely that itsproximity to the coast off Fort Orford, largely affects its temperaturedistribution, and prevents the more material and increaseddifferences, which would otherwise occur between it and Fort
