The spring employed iu this instrument is adouble spiral, as may be seen in both figures ; thespirals are twisted in different directions, in orderthat they not catch in one another. The above few sentences, assisted by an exami- nation of these figures (for wiiich we have to ac- I publication of the diagrams drawn byknowledge the kindness of Mr. CLVEcax), are, we \ attachment to the ditterent ploughs ;think, sufficient to explain the structure of this j point in succession to which we stated instrument shall next week commence the attention should be directed. it during itstaking each, at page 73,. We continue our remarks Tof-dressing^ In examining the conclusions quotedlast week as having been arrived at bj experi-menters upon this subject, there are several factsworthy of notice. Not only is the pcctdiar actionof each manure confirmed, in each case, by severaldistinct trials by the same experimenter, but thesame peculiarities of result are developed, and similarconclusions are deduced from them, by bolh expe-rimenters, though acting- far apart—a circumstancewhich, considering the circumstances under whichthe trials were made, speaks much for the trust-worthiness of the conclusions as points of pi-acticefor the consideration of the farmer. Again, it is equally worthy of remark, both asafuither evidence of the value to the agriculturistof these investigations, and as a proof of the use ofwell-digested practice to theory itself, that the de-ductions which we have quoted not only agree withand confirm each other, but
