FARMERS' REGISTER 



Having made iliese fjeneral rrmarks on the 

 rlimnteof the diflerenl, parts of Franco, we shall 

 iiexl proceed to lay lielbre our readers an ahplract. 

 of the most careful ineteorolop;ical ol)servalioMs, as 

 lliey respect the thermometer, barometer, wind.? 

 »nd rain. 



I. The annual heat of London and Paris is 

 nearly the same ; hut, from the hetrinninii of April 

 to the end of Ociober, ihe iieat is irf eater at Paris 

 than at London. If the aimual temperature of 

 ijondon be re|)resented hy 1000, the averajre de- 

 <;ree of rold in .laniiary by 1000, and the averao;e 

 (lefiree of heat in July by 1000, the annual tem- 

 perature of Paris may he represented by 1028 ; the 

 uveragft degree of col<l of Paris in Januar}' by 

 1040 ; and of heat in .July by 1037. The annual 

 temperature of I^ourdeaus will be represented i»y 

 1090 ; the average degree of cold in January by 

 925; and the average derrree of heat in July by 

 1139. The annual temperature of Monipellier 

 •will be represented by 1170 ; tlie averaire degree 

 of cold in January by 850; and llie average de- 

 gree of heat in July by 1196. 



In the centre of France, the greatest heat 

 averages 27 degrees of Reaumur's thermometer, 

 nnd the greatest cold 7 deirrees: in the north of 

 France, the greatest heat is 23° 2', and the least 

 G° 6' ; in the east of France, the greatest heat is 

 24° 3', tlie least 9° 5' ; in the west of France, the 

 greatest lieat is 24", and ilie least 6°. In the 

 pouth-east, at Monipellier, the greau>st lieat is 

 23° r, the least 5° 7'. At Marseilles, the mete- 

 orological observations of nine successive years 

 gave an average of 25° 3' for the greatest heat, 

 and 3° 1' for the least. 



I!. In the neighborhood of Paris, the baro- 

 meter never coniiiujcp tv.'euty-liiur hours without 

 changing. The barometer rises and falls sooner 

 in the western districts than in the easlern. M. 

 .Burckhardt, afier 15,000 hnromeirical ol servation 

 in order to calculate the iiiflnence of the winds on 

 the barometer in France, found that tlie souih 

 wind gave, for a menn height, 27 inches 11.3 

 lines, while an east wind raised tlio mercury to 

 38 inches 1.9 line. He also (ound, that the height 

 of the baromeier'ion the Mediterranean shores of 

 France was 2S inches 2.2 lines, while its hein-ht 

 on the At'aniio shorfs was 28 inches 2.8 lines. 



In the centre of France, liie greatest heitfht of 

 the mercurj'in ihe liorometer, on an average of 

 Keveral years, is 28 inclies5.7 lines, itslenst heiirht 

 27 inches 3.3 lines : in the unrih of France, the 

 jjreatest lieieht is 27 inches 10.10 lines, tlie least 

 26 inches 8.5 lines : in the west, the average 

 lieight of the mercury in the barometer is 28 inches 

 3 lines: in the north-east, at JMontpcllier, the 

 greatest height is 28 inches 5.8 lines, the least 27 

 inches 6.5 lines. At Marseilles, the greatest 

 lieight of mercury in the bi-rnmeler is 28 incites 

 7.2 lines, the least 27 itichcs3.7 lines. 



ill. It app<>ars from the result of observations 

 made liy M. Colie, at 86 ditlerent [)lace.sin France, 

 that along the whole south coast oftliat kincdom, 

 the wind blows most frequently from the north, 

 jiorth-west, and norlh-easi: on the west coast, 

 fiom the west, south-wesi, nnd north-west; and 

 • 11 the norlh coast, h-om the south-west. In the 

 interior parts of I'V.'.nce, the south-west wind 

 blows most liequonlly iu 18 places ; ilie west wind 

 in 14 ; the north in 13 ; the soulb in 6 ; the north- 

 east in 4 ; tlie 6outh-eaf?t in 2 ; the east and north- 



west each of them, in one. About Dunkirk, ac- 

 cording to the same author, the prevading wind.^ 

 are the aoiuh-west. As, however, the result of 

 other observations difler from those given by M. 

 Cotle, we shall subjoin them. 



Aceordingto these observations, in the centre 

 of France, the prevailing wind.s are the south- 

 west and north-east ; in the northern districts the 

 south-east wind is most common ; in the eastern 

 districts the north ami south- west winds ; in the, 

 west ol France the north-east is the [irevailing 

 wind ; in the south-east at JMonipel'ier, the norlh 

 and north-east are ihe prevailinrj winds; and at 

 Marseilles the south-east and north-west. 



IV. TTie mean (juanlily of rain that falls at 

 Paris is 22 inches ; the evaporaiion is frenerally 

 greater than the rain; the mean evaporation beint*' 

 33 inches. In the centre of France, the averaoo 

 quantity of rain is rather more than 20 inches ; the 

 number of rainy days in the course of the year 

 164. In the norlh of France there are 126 rainy 

 days ; in the east 145 ; in the west 150 rainy days; 

 in the south-east, at JMontpellier, there are 74 

 rainy days, and the quantity of rain is u|iwards of 

 27 inches — a proof of the violence ofihe rain when 

 it does Jiill. At Marseilles, the quantity of rain 

 is rather more ihan 21 inches, find the number of 

 rainy days 57. 



TIIK DRAG LOG AND COULTER PLOUGH. 



From Uie Centreville Sentinel. 



Sir: — I desire to draw the atlenlion ol"your 

 agricultural readers to two implements which I 

 used lasi year in the cultivation of my corn crop; 

 ihe dratr loiT and the coulter plough. I look iheru 

 from the Farmer's Register, to which I am much 

 indebted lor useful inlbrmaiion in my aizricuhural 

 pursuits. Perhaps my uolicms of the beneiits of 

 these implements can be best conveyed by an 

 account of the cultivation of my crop. 



I flushed the ground with Chenowiih's plough, 

 No. 9, early in the season, to the depth of the soil, 

 and as the uround was ploughed, lolknved quickly 

 with the drag log, whicli jiulverisee and reduces it 

 much better than the revolving roller. 1 then ran 

 over it vviih the large s|)ike-iooih harrow, and 

 checkered it at the distance of lour leet each way, 

 with the coulter plouirh, and after planting covered 

 with the spike-tooth htirrow. When the corn rose 

 so as to be seen distinctly, I ran the coulter ploughs 

 close to the rows, and ran over it ayain transversely 

 with the spike-'ooth harrow. Alter clearing and 

 thinning, as soon as the grass benan to grow, I 

 ran the coulter plouirh lour times in each row, 

 crossing with rank cultivators, and shortly before 

 harvest gave it the same cultivation 'reversed. 

 This wa.? the entire cultivation — I never used a 

 hoc except lor ciearinij. ]>/f y crop was much larger 

 than any I ever made, 1 do not mention the quan- 

 tity, as it was not put through acorn barrel, but 

 ascertained by corn house measurement. I be- 

 lieve I derived much benefit from the culiivation, 

 thou<rh I do not attribute the increased product 

 entirely to it ; my lands are under improvement, 

 principally by marl and marsh mud. I ijaiher but 

 linv lilades and cut no tops. My corn fields were 

 heavily set with blue urtiss, I never so well sub- 

 dued it, and accomplished my cultivation with so 

 much ease.
