Before the time of Todleben's arrival, the Star Fort had been examined by engineers, and it was soon ascertained to be so faulty in construction as to be likely to be of comparatively little use. Seeing what the faults of the work were, and seeing what ought to bo done in order to make it a good fort, the engin- eers at once went on to commence the works which were needed for the purpose. But one of the conditions in which they were called upon to act, they failed to bring into their reckoning. They left out the condition of time.
