JtiE"RE again I can meet the wishes of the Board, and give 

 them the information they require from actual experiment, 

 and on a very large scale. This soil, of \\hich there arc 

 thousands of acres in SufFuik, is in that district called clay; 

 but I believe there is no p\ire clay in that county. The 

 lands having a greater or smaller portion of calcareous mat- 

 ter in them, are consequently of a better quality than the 

 clays in Surrey and Sussex, though they were in no higher 

 repute until within these twenty years. A manor farm near 

 Eye was offered for sale about fifteen years since, when I 

 purchased it, much against the inclination of my friends, 

 who joined in the general cry of the farmers, and pro- 

 nounced the lands the poorest that ever crow flew over. 

 This did not discourage me. I found a proportion of cal- 

 careous earth intermixed with the clay on the surface, and 

 at two and three feet below the smiace a stratimi of fine 

 marl in almost every field. The estate was so depreciated 

 that I did not attempt to let it. Of the two hundred and 

 thirty-five acres, of which the whole consisted, the major 

 part was old sour grass lands, full of water quitch, over- 

 run with black and white thorn, bushes, and pollard trees. 

 I began my operations by grubbing the thorns and trees,
