(1860) 12,075; (1897) 20,705. First mentioned in 1155, Byelaya Tserkov was destroyed during the Mongol invasion of the 13th century. In 1550 a castle was built here by the prince of Kiev, and various privileges were bestowed upon the inhabitants. From 1651 the town was subject alternately to Poland and to independent hetmans (Cossack chiefs). In 1793 it was united to Russia.

It is first mentioned in 1147. It belonged to Lithuania in the end of the 14th century; and in 1468 it was raised to the rank of a principality, dependent on that country. In the end of the 15th century this principality began to attach itself to the grand-duchy of Moscow; and by Ivan III. it was ultimately united to Russia. It suffered greatly from the Tatars in 1507, 1512, 1530, 1536 and 1544. In 1826 the empress Elizabeth died here on her way from Taganrog to St Petersburg. A public library was founded in 1858 in memory of the poet Zhukovsky, who was born (1782) in a neighbouring village. The industries comprise tallow-boiling, oil-manufacture, tanning, sugar-refining and distilling. There is a trade in grain, hemp oil, cattle and tallow.

In the 17th century it suffered repeatedly from Tatar incursions, against which there was built (from 1633 to 1740) an earthen wall, with twelve forts, extending upwards of 200 m. from the Vorskla to the Don, and called the Byelgorod line. In 1666 an archiepiscopal see was established in the town. There are two cathedral churches, both built in the 16th century, as well as a theological seminary. Candles, leather, soap, lime and bricks are manufactured, and a trade is carried on in grain, cattle, wool, honey, wax and tallow.

BY-LAW, or Bye-law (by- being used in the sense of subordinate or secondary, cf. by-path), a regulation made by councils, boards, corporations and companies, usually under statutory power, for the preservation of order and good government within some place or jurisdiction. When made under authority of a statute, by-laws must generally, before they come into operation, be submitted to some confirming authority for sanction and approval; when approved, they are as binding as enacted laws. By-laws must be reasonable in themselves; they must not be retrospective nor contrary to the general law of the land. By various statutes powers are given to borough, county and district councils, to make by-laws for various purposes; corporate bodies, also, are empowered by their charters to make by-laws which are binding on their members. Such by-laws must be in harmony with the objects of the society and must not infringe or limit the powers and duties of its officers.

BYLES, MATHER (1706-1788), American clergyman, was born in Boston, Massachusetts, on the 26th of March 1706, descended, on his mother's side, from John Cotton and Richard Mather. He graduated at Harvard in 1725, and in 1733 became pastor of the Hollis Street church (Congregational), Boston. He held a high rank among the clergy of the province and was noted for his scholarly sermons and his ready wit. At the outbreak of the War of Independence he was outspoken in his advocacy of the royal cause, and after the British evacuation of Boston his connexion with his church was dissolved. He remained in Boston, however, and subsequently (1777) was arrested, tried and sentenced to deportation. This sentence was later changed to imprisonment in his own house. He was soon released, but never resumed his pastorate. He died in Boston on the 5th of July 1788. Besides many sermons he published A Poem on the Death of George I. (1727) and Miscellaneous Poems (1744).

His son, Mather Byles (1735-1814), graduated at Harvard in 1751, and was a Congregational clergyman at New London, Connecticut, until 1768, when he entered the Established Church, and became rector of Christ church, Boston. Sympathizing with the royal cause, he settled, after the War of Independence, in St Johns, New Brunswick, where he was rector of a church until his death.
