 in this cause, and offers the following premium: 2,000 francs 

 ($400) for an essay on the various building materials, incombus-

 A premium of 3,000 francs ($600) for new processes, new mate- 

 rials or methods of building of incombustible houses.

Chou-Colza (Cabbage Colza,) Brassica oleracea campestris, a 

 crucifer, although planted chiefly for oil, is good also as forage. 

 When that is the object, it is sown broadcast upon the turned

 to it for oil and for feeding cattle, and for other purposes. Light 

 soils suit it best, but a crop of it never fails on lands of the most 

 inferior description — on barren, sandy land where no other vege-
