The two latter are the warmest points recorded in their States. 
Lapwai, Kooskooskia valley, latitude 46° 27', longitude 1179, altitude 1,000 feet; 2} years’ 
observations for temperature gives: spring, 519.0; summer, 709.3; autumn, 019,2; winter, 
369.9; year, 529.4. 
Walla-Walla, latitude 46° 03’, longitude 118° 25’, altitude, 1,396 feet; 1} years: spring, 51°.9; 
summer, 73°.1; autumn, 539.6; winter, 34°.1; year, 53°.2. Dalles, latitude 45° 36”, longitude 
120° 55’, altitude, 300 feet; 31 years: spring, 539.0; summer, 70°.4; autumn, 529.2; winter, 
359.6; year, 529.8. Of these, the mean may represent the climate of the Great Plain and of 
the valleys connected with it up to latitude 49°, which are about of the same or a lower eleva- 
tion, giving us: for spring, 519.9; summer, 117.2; autumn, 539.0; winter, 359.6; year, 529,7. 
The following places may be compared with this or with each separately: Paris, (France,) 
latitude 48° 50, spring, 509.6; summer, 649.5; autumn, 529.2, winter, 319.8; year, 519.3. 
Sebastopol, latitude 44° 36’: spring, 519.6; summer, 109.6; autumn, 539.7; winter, 859,9; year, 
539.0; and the other places in southern Russia already compared with Nebraska.

With respect to moisture, no records exist for Lapwai, but the same remarks шау € applied 
as are made on Bitter Root valley; Walla-Walla and the Dalles, however, are drier in climate, 
as shown by the records, Fort Walla-Walla, 1j year's observations: spring, 6.40; summer, 2.85; | 
autumn, 4.54; winter, 1.10; year, 20.89 inches. Dalles, 3} years: spring, 2.63; summer, 0.42, 
autumn, 4.16; winter, 7.11; year, 14.32 inches. Mean: spring, 4.51; summer, 1.63; autumn, 
4.35, winter, 7.11; year, 17.60 inches. | 
Taking either the mean or the lowest as the average for the whole of the Great Plain, in 
find that they compare favorably with Nebraska, and, consequently, with southern Russia, whe, 
as we have seen, they surpass both in temperature. Actual experiment has shown the parteci 
success with which nearly all crops of the middle United States can be cultivated in the 
Walla-Walla valley, and at several other points near the Great Plain. Compared with other
