of cut sets.

Now if we look at the next Table, No. 2, which shows the average 
results of sixteen trials during the last four years with eight varieties, 
we will see that whole sets give slightly better results, with an increase of 
9 cwt. of saleable potatos per acre. From this experiment the conclu- 
sion can be drawn that there seems to be very little difference between 
planting whole and cut sets, but if anything the average results of the 
last four years are in favour of whole sets. 
The third point was : — 
To try the effect of different-sized sets, the object being to see 
which is the most profitable size to plant, and if it is wise to cat small 
sets. 
In each case the same variety of potato was planted, viz. ' Maincrop, 
and the ._}- of an acre was weighed. The sets were passed through 
riddles of different-sized meshes and weighed, an average weight of 
the sets being taken. 
There wwe six sizes tried, averaging respectively! mch in diameter^ 
If inch whole, IJ inch cut in two. 1^ inch, IJ inch, and 2^ inch. The 
weights were respectively 1 oz., 1-37 oz., 0-68 oz., 2-6 oz., 3-9 oz., and 
5*4 oz. 
^ye find that seed weighing from I'oT to 2-5 oz. each, or those which 
pass through IJ-inch riddles, but not through 1^ -mch riddles, produce the 
most economical results, as shown in Table No. 3, when we consider 
the cost of seed per acre ; seed weighing 1*37 oz., or that which passed 
through 1^-inch riddle, but not through IJ-inch, gave a profit of 
£2. 2s. Qd. per acre ; those sets which passed through l|-inch, or weighed 
2*6 oz., left a profit of 10s. 3J. per acre ; but all others gave a loss.
