FIXED TALLAGE 141 the yearly tallage and go to the good near-by towns of Raven- sered and Hull, which have good harbours growing daily, and no tallage1'.1 Here we see a fixed sum being exacted, despite the fact that towns like Hull, with great attractions to the serf, were growing up and daily recruiting in part from dissatisfied men, such as heavily tallaged Hedon could provide. Later on we shall see how these burdens drove men to consider how they could end such conditions. Fixed or "at will", tallage was an important item in the manorial income and had to be forthcoming. It was usually exacted at Michaelmas,2 sometimes from each individual, but often assessed on the vill or manor as a whole.3 The Gloucester Cartulary gives us a great deal of information about the way in which the tax was assessed. The serf pays "each according to his land and the number of his animals", and these animals all have their value;4 or sometimes he is assessed on the number of acres he holds,5 or again the serfs are assessed "in communi",6 and probably left to work out the individual payments for themselves. Yet whatever method of collection was in force, tallage re- mained a hated sign of inferiority, and men tried to get rid of it in the only way possible to them. They "bought their blood" free of this, as they had to do of other servile incidents, and found it to their advantage to commute the payment for an added general charge on each holding.7 Although this made little or no dif- ference to their annual outgoings to the lord (assuming the tallage to be steady) yet it meant that henceforth it formed but one item in the rents of assize8—that lump sum each man paid to bis lord, and which hid within itself who knows what of ancient rents, charges, personal fines and dues.
