Cohasset was officially incorporated as a separate town in 1775. Originally, Cohasset was part of Suffolk County until 1793, when the southern part of Suffolk was set off as Norfolk County. In 1803 however, Hull and Hingham joined Plymouth County that left Cohasset as an exclave of Norfolk.

Here is where a good concrete man draws upon his real knowledge of concrete, where he needs to know something not covered in specifications, and which he can know only from his own training and experience. A good concrete mixture, whether lean or rich, must be such that it will go into the forms and fill them without excessive labor in webbing or spading. We put the word fill in italics because we mean that the forms should be filled with concrete and not with air-holes and pockets. If the mixture is not well graded from cement to coarse aggregate, it will not fill properly, and no amount of water will correct this fault. What a concrete mixture needs to fulfill this requirement is a certain degree of plasticity or workability, a property which is hard to define, but one which we can illustrate in the following way: Suppose we make up a concrete mixture by starting with a rich bricklayer's mortar and adding to it gradually some course aggregate. At the start we have the mortar alone, which is very plastic and workable; it spreads easily, it can be made to fill any kind of a mold with little effort, and the water does not tend to separate from the mass. As we add the coarse aggregate these qualities become less marked; the mixture becomes harsher, it spreads less easily, more work is required to put it into a mold without leaving air-pockets, and the water tends to separate from the other ingredients. As a rule, this addition of coarse aggregate cannot be carried beyond a proportion of two volumes of aggregate to one of mortar without overloading the mixture and cutting its plasticity or workability below what is required for good concrete. On this account concrete proportions have almost always been required to have at least half as much fine aggregate as coarse, etc. This is hardly satisfactory in present-day practice, however, because such aggregates as crushed stone and crushed slag require more mortar to "carry" them than a rounded aggregate, and a poorly graded aggregate of any kind requires more mortar than a well-graded one. Further than this, the stone- carrying capacity of a mortar depends not only upon the richness of the mortar, but also on the gradation of the sand in the mortar. Everyone who has mixed and handled concrete knows that coarse sand or stone screenings make harsh working mixtures. We cannot specify a definite procedure that will insure good concrete mixtures under all circumstances. This depends upon the peculiarities of the aggregates available. But when a mixture will not go into place with a reasonable amount of effort and fill properly, there is something wrong with it, and some adjustment is needed. For this purpose admixtures of hydrated lime and other fine powders are sometimes used, or the desired improvement may be brought about by increasing the quantity, of sand. The disadvantage of using admixtures is that additional material has to be delivered to the job, and pound for pound they cost more than cement. The advantage of using an admixture, therefore, must, for economy, be weighed in comparison with the advantage of using a little more cement, with the further thought that an admixture of cement gives added strength as well as increased workability.

One of the most serious aspects of this lack of workability is the very common tendency to compensate for it by increasing the amount of mixing water. One of the most noticeable characteristics of harsh mixtures is that the water separates readily from the mass, and when this happens to any mixture, either in wheeling or placing in the forms, it is a safe bet that the mixture is too wet. The improvement in workability by adding excess water is apparent only, for segregation of the aggregates is thereby increased, and while the concrete may appear to go into the forms more readily, it goes in less uniformly, and we have in the finished product all the characteristics of poor concrete.
