and therefore no threshing, 8 had water-pow-
ered machines, 4 had horse-powered and 5

that the flail was still used.
The Diffusion of Threshing Machines in
Northumberland. It is difficult to guage how
rapidly threshing machines came into use. Bai-
ley and Culley had, as noted, described them
as ‘genera? in the northern parts of the Coun-
ty by 1797 (Bailey and Culley 46). Three later
sources - Cobbett in 1832, Grey in 1841 and
Colbeck in 1847 - have in common the disqui-
eting factor that each was seeking to show
how very progressive Northumberland agri-
culture was (Cobbett 714; Grey 2, 178; Col-
beck 424). The threshing machine, regarded as
an epitome of agricultural improvement, may
well have been claimed to have been more
common than it in fact was.
J.A.Hellen has constructed a distribution
map of Northumberland wheelhouses (Rit-
chie 69), found either by fieldwork or on the
2nd edition 25 inch Ordnance Survey sheets
(1896-8), on which are marked the locations
of some 575 wheelhouses in existence at the
end of the 19th century (Hellen 145). Hellen
found a considerable number of wheelhouses
situated above the 500 foot contour in areas
