Mr. Presiding Justice Dever delivered the opinion of the court.
3. Action, § 68* — when not prematurely brought on guaranty of payment of bonds and interest. Where the trust deed securing bonds provides that on the failure or refusal of the maker of the bonds to pay the bonds or any of them or any instalment of interest when due and payable and if the same shall remain unpaid for a period of thirty days, then all of the bonds shall become due and payable, an action may be brought on a guaranty given to secure the payment of the bonds on a default in the payment of interest, even though the time fixed in the bonds for the maturity of the principal has not arrived. 4. Guaranty, § 12*- — when guarantor not liable for interest. WThere the maturity of bonds is accelerated by bankruptcy proceedings against the maker or by default in the payment of interest thereon, as provided by the trust deed securing them, and the principal and interest to the date of the accelerated maturity are paid, one who had guaranteed the payment of the principal and interest of the bonds cannot be held liable for interest accruing after the accelerated payment. 5. Bankruptcy, § 59* — what is liability of guarantor upon bankruptcy of debtor. There is some force in the contention that section 16 of the Bankruptcy Act was intended to prevent, in the interest of creditors, a codebtor or guarantor from escaping liability in a contract by reason of the bankruptcy of a debtor. 6. Appeal and error, § 542*- — what must be pointed out in trial court. Refusal to grant a motion to strike out the answers of a witness is not error where the grounds on which the motion is based are not pointed out to the trial court.
