This is made clear by considering the question as between C and E. Each MS. has portions not found in the other. The scribe of E furnishes his own excuse; his copy was “hurriedly written” (_raptim scriptus_). Consequently we are not surprised to find that he has dropped 81 lines found in C. On the other hand, the more careful Cambridge scribe has overlooked, as the best of copyists might, 39 lines preserved in the Edinburgh version. Upon analysis of these two groups a satisfactory test of character emerges. In one case only--C, Bk. VI. *85-*92, E, Bk. VI. 101-106--do we find an unexplained confusion, traces of two alternative accounts of one incident, a possibility to which Barbour refers in several instances. One line from C Skeat rejects because it results in a triple rhyme.[6] Having eliminated these, we find that of the remaining omissions in E two lines are the result of the misplacing of one;[7] eight lines are couplets which have been overlooked; four lines are necessary to complete couplets, so that their loss is due to sheer carelessness; while the bulk of the missing lines, 57 out of 80, is accounted for by the recurrence of the same word or words at the beginning or end of the line, whereby the eye of the scribe has run on from, _e.g._, “Toward the toun” in Bk. IX. *374 to “Toward the toun” in 374, and from “thai fand” in Bk. XIII. 446 to “thai fand,” in *450, missing all between. A parallel result is given by analysis of the 39 lines wanting in C but present in E. Six are involved in the mutual perplexity of Bk. VI.; one is merely a careless oversight, and the remaining 32 come under the main category of omission through recurrence, within a short space, of the same word or rhyme. On the whole, then, with the reservation noted above, the condition of things as between the two MSS. is quite normal; the omissions are explicable on ordinary grounds, and as the missing lines, with but one real exception, take their places again without disturbance of their neighbours, we may conclude that C and E are individual versions of a single original poem, and complementary to each other. But copyists were only mortal; an author too might see cause to alter a MS.; and the variations of reading, even with those of Wyntoun thrown in, after all supply a less serious illustration of such possibilities than do the MSS. of the _Canterbury Tales_ from the Ellesmere to the so disturbing Harleian.
