It îs manifest from these considerations, and others that might be named, that the respondent companies ought to be permitted to com- plete their line aeross that of the complainant at the earliest moment compatible with the fuU and complete protection of the rights of the latter.

It may be suggested that a bond cannot be substituted for payment of the damages. After the damages are assessed, the amount ascertained, this may be so. But the question here is, whether, in a case ����
