464 REPORT oF THE HORTICULTURIST OF THE 
appearance and notes were made on the prevalence of tip burn and 
injury from diseases. 
CROP I. WINTER 1895-6. 
During the winter of 1895-1896 a soil mixture which had given 
good results in forcing lettuce at this Station, and which in this 
report will be called Soil 1, was compared with other soil mixtures 
which differed from it only in the increased amounts of sand which 
were added to them. Soil 1 was made of 1 part sand, by bulk, 
1 part stable manure and 8 parts rotted sod from a clay loam found 
on the Station farm. The percentage, by weight, of the in- 
gredients of the different soil mixtures is shown in Table I.

The loam was prepared by piling sod in alternate layers with 
stable manure and allowing it to become pretty well rotted so that 
it was rich, friable and filled with “ fibre.” The sand was clean 
and sharp. ‘The manure was fairly well rotted horse manure. 
Sample of these soils were given to Mr. W. H. Andrews, assist- 
ant chemist, for analysis. His report of the percentages of nitro- 
gen, phosphoric acid and potash, as determined by-official methods — 
of analysis, is given in Table I. 
In these important elements of plant-food the analyses show that ~ 
Soil 1 was richest and Soil 3 poorest. This was to be expected 
because, as Table I shows, the percentage of manure was greatest
