mination. Take from these sprouted seeds 
those that are of the same size and develop- 
ment, and plant six in a straight line in each 
basket, being careful to plant all to exactly 
the same depth. Then cover the soil in 
the basket about one-fourth inch deep with 
clean, dry sand, dip the whole basket, down as 
far as the rim you have already coated with 
paraffin, into melted paraffin; cool, and dip 
again and again until it is completely covered 
with hardened paraffin for about one-sixteenth 
of an inch, and you have nearly completed 
your task. 
See that the pots have the best possible con- 
ditions of light, temperature and moisture, as 
nearly as you can make it like what they would 
have in the field, being careful to keep all the 
baskets of one set together. Water them fre- 
quently. If you have weighed some of the 
baskets as soon as planted, you will know how 
much water to supply, for you must keep weight 
as close as possible to what it was at the be- 
ginning. 
Fifteen or twenty days are enough to show 
you what fertilizer your soil most needs, and 
you can then go ahead and get it ready for 
crops. This is a test solely for soil needs, not 
for plant requirements, so it is not necessary
