AIK (GIVING) is a term commonly used 

 by gardeners, who mean by the term, 

 lowering the upper sashes of the house,

 ing, at the same time, the front sashes, 

 to admit fresh air. The openings should 

 be so regulated as to equalize the escape 

 and supply, and according to the liveli- 

 ness of the current of air desired to be
