OF. pelotc, pt-lotli; ball, from ilL. pilolu, diminutive of Lat. pila, ball). A term formerly used to designate a body of troops who fired together. In its modern sense, in the United States Army, it is practically half a company of infantry. The company is divided into two platoons, and each platoon into two sec- tions. Two or three squads constitute a section, the squad consisting of four files, a corporal and seven privates, the corporal being the squad leader. The first lieutenant is in command of the first platoon, and the second lieutenant of the second platoon. The term is obsolete in the British Army, that of half-company being sub- gtituted.

The language spoken in Northern Germany from the border of Holland to the frontier of Lithuania. It is distinguished on the one hand from Low Franconian, which includes the lan- guage of Holland, Dutch proper (see Dutch Language), and, on the other hand, from Jliddle and Upper German, which are grouped together under the name High German. In common with other Low German languages, Plattdeutsch is distinguished from High German by the fact that its surd mutes have not passed tlirough the second or High German sound-shifting. (See Grimm's Law.) There is, however, no definite line of demarcation, some of the Middle German dialects not having shifted p and f. The best criterion of distinction is the so-called ich-line which starts on the Belgian border south of Lini- burg and runs in a northeasterly direction, cross- ing the Rhine at Benrath (between Diisseldorf and Cologne), the Elbe south of Magdclnirg, the Oder just above Frankfort, and finally reaches the Slavic frontier in the Province of Posen near Birnbaum. To the north of this line the first personal pronoim has the form ik, to the south ich. Within its district Plattdeutsch is generally spoken by the lower classes, while High German is the language of the school and pulpit, and as .a rule of the educated classes. Plattdeutsch is not a homogeneous language, but consists of a number of different dialects which may be divided into two main groups: ( 1 ) Northeast Saxon, in Oldenburg, Bremen. Ham- burg, Hanover, Brunswick. Holstein, ilecklen- burg, Brandenburg, Poraerania, and East Prus- sia; (2) Westphalian, in Westphalia and the Principality of Waldeck. During the nineteenth century the dialect of Mecklenburg acquired espe- cial prominence through the writings of Fritz Renter. Historically Low Saxon is divided into ( 1 ) Ohl Saxon or Old Low German, extending from tlie ninth to the twelfth century; (2) Middle Low Saxon, from the twelfth to the end of the sixteenth century ; (3) Modern Low Saxon. Platt- deutsch, or Slodern Low German, from 1000 to the present time. In the Old Saxon period the principal literary monument is the Heliand (q.v.), a religious epic of nearly GOOO lines in alliterative verse, written about 830 at the request of Louis the Pious. Sev- eral fragments of a versification of the first chap- ters of the Book of Genesis, an interlinear ver- sion of the Psalms, and various other smaller fragments of a religious character have been preserved, besides a number of glosses and proper names. Old Saxon may also lay partial claim to the Hildebrand's Lay, the most famous of all
