Consider wither Mont Tyler or Theri Lanchest & be the firms most likely to supply heavy Cast Iron piping.
His Grace's office is also of opinion that the Superintending Engineer should send home properly prepared drawings & particulars of all the iron & metal Work which will be required for the Reservoir.
Sir Wardonnell has instructed Therson to call upon Wilson for drawings & specification in order that tender may be invited in the ordinary way for the supply of the necessary Metal Work.
Under these circumstances it will not be desirable for you to take any further action in the matter until you receive instruction from this department.
