It is characterised as a good prolific potato, and without disease 
during the lour years it has been grown in this country. It is 
not ripe for use until November or December. The competitor 
is Baron Middleton, Boisdale House, York. 
The Committee fixed on twenty localities in which to grow 
these experimental potatoes, selecting them in districts where 
potatoes are extensively cultivated, and securing as far as possible 
as great a variety of climate, soil, and method of cultivation as 
could be obtained within the United Kingdom. The hearty 
co-operation of the following gentlemen practically interested in 
the culture of the potato in these various districts was obtained. 
They undertook to grow a cwt. of each of the six kinds of com- 
peting potatoes : —

These various growers were supplied with instructions as to 
how the experiment should be conducted. They were requested 
to plant the competing potatoes in adjacent plots in the same 
field with their own potato crop, keeping each sort distinct, and 
submitting all to the same treatment as their ordinary crop. 
Each cultivator has, in answer to a series of questions, supplied 
information as to whether his district is open or wooded, and has 
much hedge-row or other timber on the land ; as to the soil, 
subsoil, drainage, and slope of the particular field in which the 
potatoes were growing ; as to the previous cropping of the field ; 
the kind of potato forming his general crop ; the processes 
followed in preparing the land for the potatoes, including a state- 
ment of the manure employed, the distance at which the seed- 
tubers were planted, and the quantity planted in relation to the
