The ground on which a tenant gets relief in equity from the forfeiture of his estate for a failure to pay rent is that in equity the landlord’s right of re-entry is given as security for the payment of the rent, and on the rent being paid the very thing is done for which the security was given. Although the payment in that case is made after it is due, on interest being paid compensation is made for the delay in performance, and on compensation being made the plaintiff is entitled to relief. Peachy v. Duke of Somerset, 1 Stra. 447. Hill v. Barclay, 16 Ves. 402, and 18 Ves. 56. Reynolds v. Pitt, 19 Ves. 134. *493Howard v. Fanshawe, [1895] 2 Ch. 581, 589. The Massachusetts cases are Atkins v. Chilson, 11 Met. 112; Sanborn v. Woodman, 5 Cush. 36. See also in this connection Stone v. Ellis, 9 Cush. 95 ; Hancock v. Carlton, 6 Gray, 39, explained in Mactier v. Osborn, 146 Mass. 399, 402.
But that does not cover the case before us. In this case the defendant entered for breach of the covenant to pay taxes as well as for breach of the covenant to pay rent. When he exercised his right of re-entry in September, 1902, not only was the tax for 1900 not paid, but the estate of the defendant had been sold because of the plaintiff’s failure to pay this tax as he had covenanted to do. The defendant’s estate had been sold to pay this tax in the June preceding the September when the defendant entered on the estate. The thing here in question secured by the right of re-entry not only has not been performed, but it cannot be performed now. The tax for 1900 has been paid and no longer can be paid by the plaintiff. The tax was paid to the collector by the application thereto of the proceeds of the tax sale. There is a right to redeem this tax title, but the tax has been paid, and the thing secured by the landlord’s right of reentry can no longer be performed by the tenant. By the very terms of the covenant secured by the forfeiture, any performance of it is at an end, and that is the end of the plaintiff’s application for relief from the forfeiture in the case at bar.
Moreover if it were permissible to look behind the terms of the covenant here in question to what might be termed its true nature and substance the plaintiff would gain nothing. If you look beyond its terms, the real substance and nature of a covenant to pay taxes assessed on the demised premises is to protect and hold harmless the landlord’s estate. When the breach of the covenant has reached the stage where the landlord’s estate has been sold to pay the taxes which the tenant should have paid, and through the default of the tenant a paramount outstanding title has come into existence, we have a breach of eoveenant for which the plaintiff fails to show that compensation can be made. It is like the breach of a covenant to insure or repair where equity does not ordinarily grant relief against forfeiture of the tenant’s estate. Mactier v. Osborn, 146 Mass. 399, 402. Hill v. Barclay, 16 Ves. 402, and 18 Ves. 56 (overruling Lord *494Erskine’s opinion in Sanders v. Pope, 12 Ves. 282, which never went to a decree, p. 294). Reynolds v. Pitt, 19 Ves. 134. Bracebridge v. Buckley, 2 Price, 200. Green v. Bridges, 4 Sim. 96.
Lord Erskine’s opinion in Sanders v. Pope was in effect that the forfeiture of a leasehold estate for breach of a collateral covenant stood on the same ground at common law as that on which the forfeiture of a bond stands under St. 8 & 9 Wm. III. c. 11, § 8, which (as Baron Parke said-in Beckham v. Drake, 2 H. L. Cas. 579, 629) “in effect makes the bond a security only for the damages really sustained.”
But that view did not prevail. It is settled that in case of waste, (Peachy v. Somerset, 1 Stra. 447,) in case of a breach of a covenant to make repairs, (Hill v. Barclay, 16 Ves. 402 and 18 Ves. 56, Bracebridge v. Buckley, 2 Price, 200,) and in case of the breach of a covenant to insure, (Reynolds v. Pitt, 19 Ves. 134, Green v. Bridges, 4 Sim. 96,) it being impossible for the tenant to show affirmatively that compensation can be made, relief ordinarily will not be given. It was this which C. Allen, J. had in mind in Lundin v. Schoeffel, 167 Mass. 465, 469, when he said of the case then before the court that it “ was not like a case where the omission caused a present injury or increase of risk to the lessors, as in the case of waste, non-repair, or non-insurance.”
The lack of recent cases in England is owing to the fact that relief is given by statute in case of covenants other than the covenant to pay rent. St. 22 & 23 Viet. c. 35, § 4, authorized relief in case of the breach of a covenant to insure, and St. 44 & 45 Viet. c. 41, § 14, in case of all other covenants except the covenant to pay rent, (see clause 8 of § 14,) in which case a bill must be brought within six months from the execution putting the landlord in possession by force of St. 4 Geo. II. c. 28. It is settled that, if a bill is brought within the time allowed for relief against a forfeiture for breach of a covenant to pay rent, the relief is given at common law. Howard v. Fanshawe, [1895] 2 Ch. 581, 589. Stanhope v. Haworth, 3 Times L. R. 34. As to the purpose of St. 4 Geo. II. c. 28, see Lord Mansfield in Doe v. Lewis, Burr. 614, 619, and Wigram, V. C. in Bowser v. Colby 1 Hare, 109, 125.
From what has been said it is apparent that we are not pre*495pared to go so far as the Court of Appeals went in its opinion in Giles v. Austin, 62 N. Y. 486, 493. The facts in that case are stated in 6 Jones & Spen. 215, and it appears that the failure to pay the taxes in that case was in fact through accident and mistake, although that was not relied on in the opinion of the court.
There is however jurisdiction to relieve against a forfeiture for breach of collateral covenants, if the breach came through accident or mistake. This was established in this Commonwealth in Mactier v. Osborn, 146 Mass. 399, following the suggestion of Lord Eldon in Hill v. Barclay, 18 Ves. 56, 62, affirmed in Bamford v. Creasy, 3 Giff. 675, 680. Bargent v. Thomson, 4 Giff. 473.
If it be assumed in favor of the plaintiff that he could have relief here on proving that it was through an accident or a mistake on his part that the non-payment of the 1900 taxes went to a sale, yet the decree in the case at bar must be affirmed. The case comes here by appeal from a decree dismissing the bill. The evidence is before us, but there is no statement of facts found or of rulings made. The decree, so far as it involves matters of fact, is to stand unless it appears by the evidence to be clearly erroneous. Brown v. Brown, 174 Mass. 197. Dickinson v. Todd, 172 Mass. 183. Edwards Hall Co. v. Dresser, 168 Mass. 136. Lundin v. Schoeffel, 167 Mass. 465. See also Blossom v. Negus, 182 Mass. 515.
It is enough that the presiding judge who saw the plaintiff on the stand may not have given credit to the excuse which he made, namely, that the sale for the 1900 tax was made earlier than usual.
We have not considered the plaintiff’s argument that there was no forfeiture of the lease. We are of opinion that in a bill in equity to be relieved from a forfeiture at law it is not open to him to make the contention that there is no forfeiture at law. Such a case comes within Pitkin v. Springfield, 112 Mass. 309, in which it was held that in a petition for compensation for land taken it was not open to contend that the statute providing for the taking was unconstitutional, or that the taking was invalid. See also in this connection Smith v. Valence, 1 Rep. Ch. 90. The case of Boston & Maine Railroad v. Graham, 179 Mass. 62, stands on its special circumstances. Whether the plaintiff could *496have attacked the forfeiture at law and filed this bill in case he was unsuccessful at law, (see Moore v. Sanford, 151 Mass. 285,) or must in such a case make his election in the first instance, it is not necessary to consider.
jDecree affirmed.
