vated screens are useful in shading and protecting the young 

 plants as well, but when used for this purpose they are usually 

 raised a greater distance above the beds. A brush screen con- 



sisting of a low frame covered with boughs, is often used, as 

 shown in Fig. 4. This is cheaper than the lath screens, and is

 directly upon the ground, especially in large beds. This answers 

 the purpose of shading, but it does not allow of weeding and it 

 must be taken off soon after the seeds germinate, or slender 

 plants will be injured in its removal. Brush screens are some- 

 times raised three or four feet to allpw of weeding. A screen 

 for frames is shown in Fig. 5. It is a simple covering of 

 muslin stretched over the top and sides of a rough frame-work.

 screens is much used by nurserymen, especially for cutting beds.
