Experiments on Manures. ^r 



on fuch poor land I Ihould think that thirteen bulliels to twenty 

 loads of this weed, taking one year with another, is about the 

 common produce. Many farmers are of opinion that one 

 load of this manure is equal to a load of cow-yard dung for 

 raifmg of wheat ; but as cow-yard dung is various in r^fped to 

 its quality, it is difficult to determine the relative value of each 

 as a manure ; within two years I have ufed more than two 

 hundred loads of this manure for wheat only, but do not find 

 it equal to good cow-yard dung by five loads in thirty. I have 

 feen thirty bufliels of rye from one acre on poor fandy land ; 

 no account was kept of the number of loads put on this land ; 

 I fuppofed there mull have been near forty. It is a common 

 obfervation, that after the crop, the land manured with this 

 weed does not produce grafs equal to that manured with yard 

 dung. This is owing to the grafs feed being carried on the 

 land with the yard dung, when there is none in the fea-weed ; 

 and a larger quantity of hay-feed ought to be fown on the land 

 manured with this weed, than on that manured with yard dung. 

 This fea-weed is made ufe of as a manure in raifing Indian corn; 

 being taken from the creek in the fummer, it continues in the 

 heap till the next fpring ; it is then ploughed under the furrow, 

 about twenty tons to the acre, and is found in fome refpeBs 

 fuperior to any other kind of manure for the raifing of Indian 

 corn, as it prevents worms and inj ury from drought. The laft 

 fummer being very dry, much Indian corn was cut off by that
