It thus appears that the right of a plaintiff to take a judgment by default and without a trial by a jury, in actions founded on claims for unliquidated damages, is the same under the new rules as it was under the .old law in force prior to January 1, 1947. The action in the case at bar was on a contract or claim for unliquidated damages.

That contention is without merit under the holding of the Supreme Court in
