After the delivery of the manure, it was refused by the pur- 
chaser and removed by the vendors. 
As the use of Basic Slag as a manure is now being widely ex- 
tended, it is desirable that farmers should be careful as to what 
they purchase under that name. The following is a case in which a 
purchaser bought a worthless article under the name of “ Slag.” 
3. Mr. George Adams, Faringdon, Berks, sent on April 15 a 
sample of what he had purchased as “ Slag.” The price, carriage 
paid, was 27 s. 6 d. per ton for credit, or 25s. per ton for cash. 
The order was given on April 8 for about hve tons. On April 10 
Mr. Adams received the following letter : — 
April 10, 1893. 
Dear Sir, — I have this day sent you sixty-four bags of slag as promised ; 
a great portion of it is soot, which I trust you will receive in good condi-

price, if you let me know early, as the matter is entirely in my hands 
until the end of this month. You must also kindly oblige me with cheque, 
less cost of carriage, as I think I told you how matters stood, and at the 
price I sold to you it will not cover working expenses. I find the rate is 
7s. 3d. per ton. — -Yours faithfully, * # * »

After analysing the sample forwarded by Mr. Adams, Dr. 
Yoelcker reported as follows : —

Oxide of iron, alumina, &c 805 
Lime ......... none - 1C000 
Phosphoric acid none 
Insoluble siliceous matter . . . . . 82'85; 
This is not basic slag at all, but an utterly worthless material as a 
manure, containing no fertilising ingredient whatever. 
On Mr. Adams forwarding the letter of April 10, given above, 
Dr. Yoelcker reported further, on May. 3, as follows : — 
The statement that the “ slag ” contains soot is not correct. I have 
made a determination of the nitrogen in the sample, and find that there is
