water, accumulate dirt and damage the paint. The coarser vines, 

 like the wistarias and trumpet creepers do best when guided in their 

 upward and lateral growth by strong wire cords firmly fastened 

 to permanent supports. In this way the vine may be taken up to 

 the second or third story and there be led out horizontally as desired. 

 Such vines need an annual pruning, and when of the desired size 

 this should be done thoroughly or else the festoons become top- 

 heavy and unsatisfactory. When trained for a piazza screen, strong 

 posts may be set a foot or so away from the eaves, and, with a cross- 

 bar or two, a skeleton is ready for the vines and the porch is free. 

 The sprays of the wistaria thus hang better than when the vine is 

 fastened to the roof, and the woodwork is preserved in better form, 

 besides there is none of the trouble of laying down the vines when 

 the painters come a class of people who are not partial to live covers 

 and act accordingly. 



The finer vines, as roses, clematis and even honeysuckles, which 

 are trained to the wire netting both perpendicularly and latterly may 

 receive the needed care of the one in charge, from time to time, 

 directly from the piazza, supplemented with a severe pruning in the 

 fall or spring as circumstances of age and growth suggest. 



An occasional turning on of the hose, if it is available, from 

 the piazza side, as the season advances, is useful in giving the vines 

 a clean appearance. Sometimes plant-lice appear and such a spray- 

 ing with the hose is helpfull in removing them and other pests. 

 Such a washing may be only an extension of the area of cleansing 

 when the floor and sides of the porch receive their occasional or 

 stated scrubbing.
