Chap. IX. Of Wheat. 127 



in the fame Spot*, but 'twas becaufe the Spot where 

 the Twenty grew, was then a little higher than the 

 reit, which in Two Years became more equal ; and 

 the thin Land was more deficient in that Third Crop, 

 than the thick Land exceeded the thin in the Fifth 

 Crop. 



In the thick the Hoe-plough went deeper, and 

 confequently railed more Pafture there ; but then it 

 went the fhallower in the thin •, and when the Land 

 became of a more equal Depth the Fifth Year, the 

 Plough and the Hoe-plough went deeper, all the 

 Piece being taken together-, for the Crop could be but 

 in proportion to the different Pafture, allowing ibme- 

 what for the more or lefs Seafonablenefs of the Year. 



The Soil, in this our Cafe, cannot be fupplied in 

 Subftance, but from the Atmofphere. The Earth 

 which the Rain brings can do it alone, if it fall in 

 great Quantity ; for by Water, 'tis plain, the Earth 

 which nourifTied Helmont's Tree was fupplied ; for 

 the Tin-cover of the Box wherein it flood, prevented 

 the Dews from entering. 



Dews muft add very much to the Land, thus 

 continually tilled and hoed ; for they are more 

 heavily charged with terrefirial Matter than Rain is, 

 which appears from their forcing a Defcent through 

 the Air, when 'tis flrong enough to buoy up the 

 Clouds from falling into Rain : And Dew, when 

 kept in a Veffel long enough to putrefy, leaves a 

 greater Quantity of black Matter at the Bottom of the 



Imagination often deceives us by Arguments falfe or precari- 

 ous; but Reafon leads us to Demonstration, by Weights and Mea- 

 fures : Yet this Prejudice will vanifti at Harveit before weighing; 

 for then all thofe wide Intervals that were bare, will be covered 

 with large Ears interfering to hide them quite, and make a finer 

 Appearance than a ibwn Crop. But 'tis obferved, that the Cone- 

 wheat makes the fineft Shew, when you look on it lengthways 

 of the Rows, both at Harveft, and a confiderable time before 

 Harvcft.
