are in no way different from those of all other primitive or barbaric peoples. The conclusion to be drawn from our investigation of the names and series of the months is therefore the following. In order that the month may be distinguished from others it is named after an occupation or natural phase which takes place while the month lasts, being described commonly by means of the addition ‘moon of the --’, but not seldom simply by the name of the natural phase or the occupation respectively. Any natural phase or occupation can originally give its name to a month, and hence arises an indefinite number of such terms. When any period of the year is without important natural phases and occupations, the months in this period are not named. At first, therefore, the names of the months are of an occasional, incidental character: the orientation of them follows from the general acquaintance with the phases and occupations of the natural year. As the result of a gradual selection in the daily usage of the names a less unstable, and in the end quite fixed, series of months is formed, which on account of the length of the natural year must comprise 12 to 13 months. The result is a difficulty which formerly was not felt, owing to the fluctuating character of the names of months, for the natural phases and the moons are pushed out of their mutual relationship, and this naturally leads to the question how many months the year includes, i. e. to the necessity of the intercalation. For the moon-month, which begins with the new moon, is a natural unity, which cannot be broken up. CHAPTER VII. CONCLUSIONS.
