BOG (from Ir. and Gael, _bogach, bog_, soft), a tract of soft, spongy,
water-logged ground, composed of vegetation, chiefly mosses, in various
stages of decomposition. This vegetable matter when partially decomposed
forms the substance known as "peat" (q.v.). When the accumulation of
water is rapidly increased by excessive rainfall, there is a danger of a
"bog-slide," or "bog-burst," which may obliterate the neighbouring
cultivated land with a deposit of the contents of the bog. Destructive
bog-slides have occurred in Ireland, such as that of the Knocknageeha
Bog, Rathmore, Kerry, in 1896, at Castlerea, Roscommon, 1901, and at
Kilmore, Galway, 1909.

There is a French game of cards called "bog," said to be of Italian
origin, played with a piquet pack on a table with six divisions, one of
which is known by the name of the game and forms the pool. It was
fashionable during the Second Empire.

Jankowe in Lower Silesia on the 7th of September 1690. At first a page

(orphanage) at Halle, where he engaged in spiritual work and in
