579. ~till I had found~. The language is extremely condensed here, the
meaning being, 'I began my flight, and continued to run till I _had
found_ you'; the pluperfect tense is used because the speaker is looking
back upon his meeting with the brothers after completing a long
narration of the circumstances that led up to it. If, however, 'had
found' be regarded as a subjunctive, the meaning is, 'I began my flight,
and determined to continue it until I had found (_i.e._ should have
found) you.' Comp. Abbott § 361.
