 mercial establishments. There a large bench 

 in a house, or perhaps an entire house, will 

 be devoted to the purpose. Cuttings that 

 are propagated before the first of April 

 will do well in a good position in any house 

 if well shaded. After that date what is 

 known as a north-side propagating house 

 is more desirable for the purpose. This 

 house is made by practically putting a 

 partition lengthwise of an even-span green- 

 house that extends east and west, thus form- 

 ing a low, narrow house at the north side 

 of a three-quarter span house. Architect- 

 urally the propagating house may be distinct 

 from the other. It is generally from six 

 to seven feet wide, with a bench three to 

 four feet wide. The most of the heating 

 pipes are placed under the bench, the 

 sides of which extend below the bottom, 

 sometimes to the floor, thus forming an 

 enclosure for the pipes and maintaining 

 a higher temperature under the cuttings 

 than that of the atmosphere above them, 

 producing what is termed "bottom" heat. 

 Cuttings of most genera of plants root more 

 quickly, and often better, for having a
