 few inches above the outside grade. As most Green- 

 houses are necessarily built low to accommodate the 

 idants, a small terrace around them adds to the eleva- 

 tion and the good appearance of the structure. It will 

 usually be best to keep the tloor of a Greenhouse all on 

 one level. When the variation in the grade of the ground 

 is not too great, the floor line should be at the highest 

 point of the grade. In the case of a long 

 house, the floor line is sometimes made the 

 same as the natural grade, but such an ar- 

 rangement is to be avoided when possible. 

 For locations on a hillside, the different 

 apartments may have different floor levels, 

 with necessary steps between 

 them. 



All the sod and loam should be 

 removed from the space to be 

 covered by a Greenhouse, and all 

 the filling necessary made with 

 subsoil. The latter should be laid 

 in thin layers and each wet down 

 and thoroughly tamped. Loam 

 used for filling under a Green- 

 house is apt to become sour, and 

 will continue to settle for a long 

 time, causing much trouble and

walls take up less room in th< 



house than stone, and are usually 



less expensive. The foundation walls should be extended 



down to a point below the frost line, generally 3 or 4 feet 



deep, and are usually raised about 2 feet above the grade.

 struction has been extensively adopted by florists and 

 large growers of cut-flowers, though generally with the

 somewhat increased over an all-wood construction, but
