Every material issuable fact must be alleged in order to admit the necessary evidence in support of it. Thompson v. Thompson, 12 Tex., 327; Mims v. Mitchell, 1 Tex., 443; Lemmon v. Hanley, 28 Tex., 219.

To authorize a recovery for the loss of profits, as damages, occasioned by suspension of their milling operations, it was essential for the appellees not only to prove that such suspension was caused or rather continued by the failure to promptly forward the cylinder, but also that such facts had been communicated to appellant as would have reasonably indicated the result which would or might have been expected to flow from a delay in forwarding the same. Such elements of damage would not necessarily result from such delay. Nor are they such as might be reasonably supposed to have entered into the contemplation of the respective parties, at the time the contract was made, as the probable result of its breach. Hadley v. Baxendale, 9 Exch., 353; Jones v. George, 61 Tex., 349.

As these facts were such as it was necessary to establish by evidence before a recovery could be had for such elements of damage, it inevitably follows that it was equally necessary that they should have been alleged.

From this conclusion it will be seen that the court erred in permitting the appellee, Tom Darnell, to testify, over the objections of appellant, that he informed the agent at the time the cylinder was delivered that their “ mill was idle,” and they “ in a hurry to get it forwarded to Baltimore.”

In reference to the rule for the measure of damages, it is sufficient to quote from Hadley v. Baxendale, supra: “ Where two parties have made a contract which one of them has broken, the damages which the other party ought to receive in respect of such breach of contract should be such as may fairly and reasonably be considered either arising naturally, L e., according to the usual course of things, from such breach of contract itself, or such as may reasonably be supposed to have been in the contemplation of both parties, at the time they made the contract, as the probable result of the breach of it. Now, if the special circumstances under which the contract was actually made were communicated by the plaintiff to the defendants, and thus known to both parties, the damages resulting from the breach of such contract, which they would reasonably contemplate, would be the amount of injury which would ordinarily follow- from a breach of contract under these special circumstances so known and communicated. But, on the other hand, if these special circumstances w-ere wholly unknown to the party *642breaking the contract, he, at the most, could only be supposed to have had in his contemplation the amount of injury which would generally arise, and in the great multitude of cases not affected by any special circumstances from such a breach of contract.”

The other questions presented are such as need not be considered. Our conclusion is that the judgment ought to be reversed and the cause remanded.

Reversed and remanded.
