Further that the trench would be backfilled with satisfactory material free fro® large boulders or rook and that we would be advised when backfilling was commenced so that we could examine the fill material and observe the operation* Between Friday, September 1^, and Monday morning, September 17, without previous advice to us the trench was backfilled using the material originally excavated from the trench which contained a large peraentage of large pieces of caliche and boulders not suitable for backfilling and so far as we can ascertain no gravel or crushed rook was tamped under and around the pipe nor was the blocking removed*
