Use of affidavit without order
5. Where a party desires to use at the hearing an affidavit by any witness as to particular facts as to which no order has been made, he may, before the beginning of a period of six days ending on the day of the hearing, give notice, accompanied by a copy of the affidavit, to the party against whom it is to be used, and unless the last mentioned party, before the beginning of a period of three days ending on the day of the hearing, gives notice to the other party that he objects to the use of the affidavit, he shall be taken to have consented to the use thereof and the affidavit may be used at the hearing unless the judge otherwise orders.
