66 ON RYE. 



And here I would suggest that I do not considei' the experi- 

 ment as we have conducted it, quite complete. To render it 

 more so, in the first place, in ploughing in the weeds, I would not 

 turn a furrow after the dew had evaporated. I have no doubt 

 but that a large portion of that fertilizing quality in the soil, 

 which (during the summer months) is continually exhaled from 

 the earth, is by the dew brought again within our reach, and it 

 would be wise to avail ourselves of the opportunity of again 

 burying it in the soil. And in the second place, I would by all 

 means use a heavy roll after each ploughing. It would fill all 

 the cavities left by the plough, and by pressing the soil more 

 closely to the weeds, at once hasten their decomposition and 

 very much retard the evaporation from the soil. 



But the land is not only very much enriched by this process. 

 There is I conceive no method by which it can be so effectually 

 cleaned. Three times during the season, a fresh surface is pre- 

 sented to the atmosphere, and each time, as the decaying vegeta- 

 ble matter increases in the soil, so is the exciting cause augment- 

 ed to make a more vigorous effort. We have in this manner 

 gone over nearly all our land which is infested with charlick, and 

 the diminution of the weeds is quite sufficient to warrant the ex- 

 pectation, that in'a few years it may be comparatively eradicated- 

 Very respectfully.

Haverhill, Aug. 1, 1832. I have this day measured a lot 

 of land belonging to Mr. Keely, on which is a crop of rye, and 

 find it to contain one acre and thirteen rods.
