with a View to the most Profitable Crop. 55 
yield to the lateral pressure and jerks produced by the action 
of the horse. 
The ground, having been thus brought into a proper state, 
received a good dressing of compost, consisting of a mixture 
of stable manure, sea-weed, street sweepings, and sea-wrack, 
collected at a spot where an eddy causes a collection of a 
variety of different matters: the manure was thrown into 
the furrows turned out to receive the potatoes. In one 
instance sea-weed was used by itself quite fresh, and the 
potatoes planted upon it. 
The course pursued was to turn out a set of ten furrows, 
3 feet apart, from centre to centre, occupying thus a 
width of 30 feet. In these first furrows the potatoes 
were planted at distances of about 3 feet apart between 
the sets. In a second set of ten furrows, the potatoes 
were planted at distances of 18 inches apart. 
A set of 12 furrows, occupying a like space of 30 feet 
in width, was then turned out; and in these the potatoes 
were planted at distances of 30 inches apart. 
The potatoes were planted about the end of July or 
the beginning of August; the season was, as every body 
is aware, very dry: notwithstanding, there were very few 
failures, except in those rows which were manured with 
raw sea-weed,—where it would appear that sets had decayed. 
The potatoes at the lower end of the field, where the soil 
was more sandy, were ready for digging in February ; while 
those at the upper end showed the haulm quite green till 
March. 
The mode which I adopted in order to ascertain the rela- 
tive amount of crop upon a given area of land was as fol- 
lows :—a length of 30 feet was measured along a single ridge 
of potatoes, noting down the average distances between the 
ridges and counting the number of sets contained in the
