It is objected that the action upon the drafts in suit was prematurely .brought. It is claimed that the evidence *293shows that they were drawn upon a fund in the bands of the plaintiffs, wbicb was created by tbe chattel mortgage and $5,000 note, and that an action on them could not be maintained until the six months’ credit given on this note and mortgage had expired. But the obvious answer to this objection is, that it is expressly stated in this mortgage that it is given merely as “ collateral security ” for the payment of such sums of money as the plaintiffs should advance to the defendant. It was not provided that six month’s credit should be given on the moneys advanced, or that the right of action should be suspended on the original indebtedness for that period. Of course, no action could be maintained upon the note and mortgage taken as collateral security until they became due. But as they were confessedly given merely as collateral security for future advances, there is no ground for saying that the plaintiffs were bound to wait until the time when these collaterals became due before they could bring suit upon the acceptances. For no right of action was suspended on the original indebtedness during the currency of the collateral security, but the money became due on such original debt according to the terms of the contract. Plant's Manufacturing Co. v. Fahey, 20 Wis., 200. In this case it appeared that the defendant had no funds hr the hands of the plaintiffs to meet these drafts, and the money paid on them was paid for his accommodation, and became due presently. This proposition seems too plain to require further remark. There is, therefore, no reason for claiming that the action on these drafts was prematurely brought.
One of the important questions in this case was, whether, after the taking of the contract by the defendant, the plan-or character of the work on the road was changed from embankment to tressel work, to his injury. It was claimed on the part of the defendant, that a material change in the plan or character of the work was made, by putting in tressel work or a wooden bridge in the place of embankment; and that this change was prejudicial to him, because he was compelled to waste dirt, in *294consequence of the substitution of tbe bridge, wbicb would bave gone into embankment in tbe place of tbe tressel work, and for wbicb be would bave secured pay under tbe contract. Tbe circuit court, however, beld that tbe plaintiffs bad tbe right under tbe contract to make this change in tbe character of tbe work, and that if, in consequence of it, earth was wasted that might bave gone into embankment 'but for such change, tbe defendant was not entitled to recover any damages therefor. Tbe clause in tbe contract relied on to sustain this view, is' tbe following: “ It is further mutually agreed, that tbe party of tbe second part may make such changes in tbe location of tbe road, as well as such variations in tbe grade lines of tbe same, as they may consider expedient, and whether such changes shall increase or decrease such work, only the actual amount of work consequent upon such changes shall be paid for, at tbe regular prices agreed upon below.” There was a further clause in tbe contract, wbicb provided that for tbe movement of earth or rock tbe same was to be paid for only once; that is, either as embankment, where this exceeded tbe excavation, or as excavation, when this exceeded tbe embankment.
Now, there was testimony in tbe case wbicb tended to show that considerable earth was “ borrowed ” and placed in tbe embankment, under tbe grade and plan of tbe road at tbe 'time tbe defendant so borrowed tbe earth, for wbicb be would be en-titléd to receive tbe contract price. Also that, afterwards, in consequence of tbe plan being changed and tressel work being substituted for embankment, tbe defendant was compelled to waste an amount of earth taken from tbe excavation equal to tbe quantity borrowed. And tbe question, therefore, became important under tbe contract, who was to sustain this loss consequent upon tbe change in tbe construction of tbe road. If, under the contract, tbe plaintiffs reserved to themselves tbe right to change tbe work from embankment to tressel work, then tbe defendant must sustain it.
*295Undoubtedly tbe plaintiffs reserved to themselves the. right,, under the clause of the contract above quoted, to make any such change in the location of the road, and in the grade, as might be deemed expedient and necessary, whether such change should increase or decrease the amount of work to be done, only paying the. contract price for any extra work consequent upon the change. The contract is clear and specific enough upon that point But a change from embankment to tressel work can hardly be said to be either a change in the location of the road or a variation in the grade lines of the same, but it is a fundamental change in the character and nature of the work. Suppose the plaintiffs had directed tressel work, piling or mason work to be put in wherever an embankment was to be made, would it be claimed that they had authority to do this under the above provision of the contract? Any such change would make a very profitable contract absolutely ruinous to the contractor. And it is apparent that if they have the right to substitute tressel work for any part of the embankment, they have the right to substitute it for the whole, and may thus make a complete and total change in the nature and character of the work We do not think the contract is fairly susceptible of any such construction. It is said on the part of the plaintiffs, that if, by the original grade line, there had been no ravine at the point where the tressel work was to be put in, and upon that plan the defendant had wasted 20,000 yards of earth at the cut, precisely as he did do, and then the next day the plaintiffs, by their power under the contract — the nature of the ground being such as to permit it — had changed the location of the road to the right or to the left so as to cross a ravine near by, requiring 20,000 yards of earth for embankment, the defendant’s labor might have been doubled by this change, but yet he could receive no compensation for this extra work under the contract But, manifestly, if he could not, it is because the plaintiffs have clearly reserved the right to change the location of the road, which involves all these possible consequences. *296But, as tbey bave not reserved tbe right-to change tbe character of tbe road-bed from embankment to tressel work, if tbey do so to tbe injury of tbe defendant, tbey should make good bis loss.
It is further said tbat tbe evidence showed that tbe original plan of tbe work - was not changed before tbe defendant abandoned bis-contract. But this was a question of fact, which should bave been submitted to the jury upon tbe evidence.
We.bave carefully considered tbe other exceptions taken by tbe defendant to tbe rulings of tbe court below, and think them untenable. But, for tbe error of tbe court in tbe construction of the contract in .the-particular already referred to, there must be a: new :trial.
By the Court. — Tbe judgment of tbe circuit court is reversed, and a new trial ordered.
