Paragraph 7 I1

Any specified work, and any protective works required by the Trust under paragraph 6(b), must be constructed without unnecessary delay to the reasonable satisfaction of the Trust, and in such manner as to cause as little damage to the canal as may be reasonably practicable and as little interference as may be reasonably practicable with the passage of vessels using the canal, and an officer of the Trust is entitled at all reasonable times, on giving such notice as may be reasonable in the circumstances, to inspect the construction of such work or works.
