The climate, or rather climates, for there are several distinct climatic areas, of the vast western half of Canada, is, however, a matter of fact and science rather than ofexi)or- ience, and an intelligent man, t hough he had never been west of Lake Supei'ioi-, noi- heard a single word about its actual weather, could predict with much accuracy what kind of climate would be met by ex])loi'ers in each of its various divisions, simply from knowing the physical situation of each. For climate is very lai-gely — almost wholly — a function, as mathematicians say, of, first, the latitude, and, second, the physical geography of the region under consideration. * Abstract of a lecture in the Soinervillc Course, delivered in Montreal, March loth, 1888. 8-2 (Ut mid ill II lliroi'il <>/ N'/'iVv/rr'.

Condensed still further, by the Selkirks, there is a copious i-ainfall and snowfall upon these mountains, and a further giving u|) of wai-mth, which greatly teinj)ers the climate ; but by the lime the Selkirks are past, the winds havt' lost nearly all theii* moisture and warmth, and have been rai'iHed by being forced to an aver- age height of seven or eight thousand feet. Hence, when they pass to the liockiesthcy are dry and cool in summer — dry and very cold in winter.

Why? Owing to theChinoolc winds, jjiit what are the Chinook wintls ? ( 'urrents of wai'in aii- — broad sheets — eataiaets — of warm aii' tailing down in mid- winter from the tojt of the UoeUies. Hut why, if the air on the ere>l, where the wide spaees of snow lie. is deadly (•1)1(1, should the lireezen deeending from those snow-tields he eiimfortably warm in winter ? Sini])ly because they do descend. Hero is the reversal of the previous condition. The air ascending the westci'n side and ai the toj) of the Kockies is colli because it is losing its moisture and becoming rariliiid ; the air descending the eastern slope becomes condensed, picks up moisture with cver\' j)art of its descent, and coi' I'Cspoudingly (levelo])s, or gives up, the latent lu^at which invai'iably acconij)anies condensation, The ('hinoolc, then, is a warm dry wind, manufactured on the spot by the condensation of the mountain air as it sweeps down, increas- ing in density, absorbing moisture, and 3ielding up its latent heat. In summer the same bi-ee/.c seems <'Ool in comparison with the fierce radiation of the baked plains; but it is e(|ually a Chinook. This wind is marvelous in its etfect. To it is duo the pleasing dryness of even the deepest gorges and nooks in the rocks in summer, while in wintei- it clears the plains Ibi* hundreds of miles away from the mountains of neai-ly all the snow — always scanty in amount — with amazing celerity.

Winter thoi-e, in fact, is neither s(» long nor so severe as on tho lofty j)laloaus fifteen hundrcako Winnipeg, the Tied River valley, and the valley of the upper Mississippi In i-espect to the climate of Manitoba and tho Saskat- chewan prairies, there is one man to whom all of us are indebted for information drawn from an untiring and early experience, and sustained by a sound Judgment. I refer to Prof. John Macoun. of the Geological Survey. His book " Manitoba and the Great Northwest,'' is a most admirable compendium of information in regard to all the natural aspects of that great region, and 1 have had it constantly before mo in wi-iting out these notes. The Canadian plains, as has already been said, stretch from Red River westward to the Rocky Mountains, and I I I the •etch , and I ■I I (h'lnti/e of the Cntni/fian Wrsf. 0:1 northward to the forosts l>cy(>nth pai;illcl of latitude in Manitoba and still hii^hei' farther west; while wheat, barley and alP the hanly vegetables attain lull ripeness on the banks of the I'eace K'ivei", in latitude 50'', —the parallel which touches the southein ex- tremity of (rreeidand. At Fort Diinvegan, on I'eace Kiver, thirteen degrees noi-th of Toronto, or nearly as far as Cuba is south of it, the winters, as 1 have said, ai-e milder than those of Manitoba or (Jntai'io; and foi' the seven months, from A])ril to Octo- ber, constituting the period of cultivation, Dunvegan and Toronto do not vary moi-e than about one-half a degi-eo in average temperature; while, as C()mj)ai'cd with Halifax, the ditfei-ence is in favor of Dunvegan. The frosts there do not lingi'i' in tiie spring as late as here in the neighborhood of Montreal, nor do they begin so early in the fall; — and eveiy^fhing which will grow here will rijjen there, in many cases with greater luxui'iance. Out of 212 species of plants seen along Peace River, near Dunvegan, 18>* grow in the vicinity of Toronto, and the I'est are such as behuig to the Saskatchewan plains. The list includes a native cactus ! In view ot" these facts, it is evident that mere diffei'crice of latitude is of small account; and when wo cojne to examine the isothermal lines marking similai'ity of mean summer temperature, we find thatlhc}' curve fai- northward, the isotherm of ai\ average >ummei' temperature of (»5", which is that of this ])art of Quebec, curving through Georgian Bay, along the .south shoi-e of Lake 8u])ei'ior, and swinging northward through Manitoba and north of the Saskatchewan almost to Peace River.

I'^arly in April, then, tlu; sun dissipates the light snow, the dry air evaporates it. leaving the ground dry, and plowing and seeding go on .simultaneously. In u tew days the seed germinates, owing to the hot sunshine. The roots rectdvo an ahundance of moisture fr. -m the thawing soil, and j)ene- Irate l<; an astonishing depth into the loosened loam. Jiy the time the rains and heal of .lune have come, abunduiico of I'oots havt' foriui'd and the cro[) rushes to quick' maturity. The enoriiious crops are owing just as mu(di to the oponiiig power of the frost a.> to the I'ertility of the soil ; this is a |)eculiai'ly favorahle etl'cct of the switl change from sharp cold to intense heat which characterizes the climate of that j'egion. The summer weather is often extremely hot — I're- quently reaching 100 degrees; but this is a scorching, not a sweltering heat. It is the direct burning of the sun's rays — not a heat resident in the air: hence you mark an in- stantaneous and grateful I'dief when you step into the shade, or catch the breeze. Sunstrokes and loss of vigor through heat, which so (>ften accompany summer days here when the mercury may not go so veiy high, arc almost un- i'liiiiah' ()/ flir (^(ttititlinti Wist. 96 lb' lilliCO irity.

This inci'casod "ener^jN' of growth has been remarkably manifested in some instances. The early spring wheat cul- tivated foi- forty years in the Selkirk settlement, before the birth of Manitoba, was originally an Knglish winter wheat. Mori' lately a winter wheat from Pennsylvania was trans- formed iiitoaspring wlieat in Maiutoba after a singleyeur's i'e|)roduction. The seed of a certain kind of Indian corn cidtivated about Winnipeg was two weeks later in maturing when sown neai' St. Loins, whence it iiad originally been brought ; but ([uiidvuess in coining to maturity is in fact, char- acteristic ot all the plants indigenous to the Northwest, and is a (|uality s]»eedily accjinred by im)»oi'ted i)lants — u point not only in agriculture, but a pretty fact for tho evolutionist to ruminate upon. Furtheimoro, the cool moist spring checks an undue luxuriance of Htom, and allows tlu; .strength of the grain- plant to be expended on the head and fruit (that is the grain) which is what the prairie cultivator, unsolicitou.s in I'egurd to manure, seeks to perfect. This vigoi' given to vegetation in cold climates is in accordance with the well formulated law that ciUtivaied plants yield theii- greatest product near the northernmost limit at which they will grow.

As for wheat — overvono inl(>rosted in those mattei's ou^-ht to lead the remarkable facts stated by Mr. J. W. Taylor, U.S. Consul :it \Vinnij)ei;', in his numerous writings and spoeidies on this subject. Hei'o a^ain it is along the northoi'ii part of ils i-ango th;it the best product is obtained. Tho tinost wheat gr )wn in luii'opo comes fi-om tho Baltic shoi-es ; and in tho United States fiom Minnesota and Dakota; and in this im|)ortant grain we have our most stiiking example of what the climate of the Canadian West is in relation to agriculture. In soulhorn Minnesota, Iowa, etc., more than two well-formed grains of wheal aie seldom fouufl in each cluster oi" fascicle forming one of tho rows in ahead In Manitoba and Assiniboia (whore tho shortness of tho straw is sur])rising to a stranger), three gi'ains are habitually found. This is an addition of ono-thii'd to tho yield of each acre. That means 30 bushels on the average instead of 20 — S15 instead of SIO an acre at present prices. But wheat gi-own along Peace River often shows four and five grains in tho cluster ! This is not tho whole of the story. Tho kernels are harder and better tilled out than southwai'd; and it is an established fact that varities of wheat classed as " soft " in the Mississippi states regain thoirtlinty texture and become " hard " in the Northwest. i I i I 4 f Climnli ul llir.
