A contract to attach property to realty and to furnish labor for so doing is held not a contract for the sale of goods. Thus, contracts to erect a building,1 a monument,2 a bridge,3 or attaching stoking apparatus to boiler,4 or setting up a steam-heating apparatus in a factory,5 are none of them contracts of sale. This rule may be referred to the principle already given,6 that if an article is to be made upon a special order and of a particular design, the contract is not within the statute.
