"It so happens that Greylock, in our immediate vicinity, is the highest mountain in the Commonwealth, and gives a view from its summit 'that for vastness and sublimity is equalled by nothing in New England except the White Hills.' And it is an ancient observance to go up from this valley once in the year to 'see the world.' We were not of the number who availed themselves of this _lex non scripta_, forasmuch as more than one visit in time past hath somewhat worn off the novelty of the thing. But a goodly number 'went aloft,' some in wagons, some on horseback, and some, of a sturdier make, on foot. Some, not content with a mountain _day_, carried their knapsacks and blankets to encamp till morning on the summit and see the sun rise. Not in the open air, however, for a magnificent timber observatory has been set up,--a rough-hewn, sober, substantial 'light-house in the skies,' under whose roof is a limited portion of infinite space shielded from the winds."--_Williams Monthly Miscellany_, 1845, Vol. I. p. 555. "'_Mountain day_,' the date to which most of the imaginary _rows_ have been assigned, comes at the beginning of the summer term, and the various classes then ascend Greylock, the highest peak in the State, from which may be had a very fine view. Frequently they pass the night there, and beds are made of leaves in the old tower, bonfires are built, and they get through it quite comfortable."--_Boston Daily Evening Traveller_, July 12, 1854. MOUTH. To recite in an affected manner, as if one knew the lesson, when in reality he does not. Never shall you allow yourself to think of going into the recitation-room, and there trust to "skinning," as it is called in some colleges, or "phrasing," as in others, or "_mouthing_ it," as in others.--_Todd's Student's Manual_, p. 115. MRS. GOFF. Formerly a cant phrase for any woman. But cease the touching chords to sweep, For _Mrs. Goff_ has deigned to weep. _Rebelliad_, p. 21. MUFF. A foolish fellow. Many affected to sneer at him, as a "_muff_" who would have been exceedingly flattered by his personal acquaintance.--_Blackwood's Mag._, Eng. ed., Vol. LX. p. 147. MULE. In Germany, a student during the vacation between the time of his quitting the gymnasium and entering the university, is known as a mule. MUS.B. An abbreviation for _Musicæ Baccalaureus_, Bachelor of Music. In the English universities, a Bachelor of Music must enter his name at some college, and compose and perform a solemn piece of music, as an exercise before the University. MUS.D. An abbreviation for _Musicæ Doctor_, Doctor of Music. A Mus.D. is generally a Mus.B., and his exercise is the same. MUSES. A college or university is often designated the _Temple, Retreat, Seat_, &c. _of the Muses_. Having passed this outer court of the _Temple of the Muses_, you are ushered into the Sanctum Sanctorum itself.--_Alma Mater_, Vol. I. p. 87.
