Agricultural Worthies. 
The powdered slag should never be mixed with ammonium 
sulphate before use, as it liberates ammonia therefrom, which is 
thus lost. When both are used to the same crop, the slag should 
be applied first. It is, moreover, undesirable to mix it with 
kainit ; or, if this be done, it should be sown at once, as the 
mixture is liable to cake and become hard. Owing to the great 
density of the slag, it is somewhat difficult to apply it evenly ; it 
is, therefore, often advantageous to mix it first with some dry 
earth or similar material.

AGRICULTURAL WORTHIES. 
I.— THE THIRD EARL SPENCER. 
With an Appended Note by the Rt. Hon. Sir Harry Verney, Bart. 
In commencing a series of papers on " Agricultural Worthies,'' 
relating more particularly to those who have been prominently 
connected with the Royal Agricultural Society, the first to 
claim attention is the eminent man whose name stands at the 
head of this notice, and who, primus inter 
pares, was foremost amongst those to 
whom we owe its inception, establishment, 
and early development. 
John Charles, third Earl Spencer, better 
known in early life by his courtesy-title, 
Lord Althorp, which he bore from his 
birth till within eleven years of his death, 
was born at Spencer House, St. James's, 
earl spencer. 1 on May 30, 1782. He was educated at 
Bom 1782; Died 1845. Harrow, and at Trinity College, Cambridge, 
where he took an honorary degree, as was usual at that time 
with persons of rank. During his first term at Cambridge he 
was, according to his own account, very idle ; but finding that 
his mother had set her heart upon his being in the first class 
in the next college examination, lie applied himself so diligently 
to his studies that in his second year this hope was fulfilled.

at Althorp by the eminent Mr. William Wyon, R.A., in the year 1841. This 
model, from which the Smithfleld Club's medal, and other medallions of Lord 
Spencer were taken, is now in the possession of the Society, having been pre- 
sented to it in March 1890 by Mr. Leonard C. Wyon,
