tection is furnished by board frames and lath shades as 

 shown in figure 23. The frames may be made of incli 

 boards or plank, and should be one foot high, four feet 

 wide, and of any desirable length. To make the lath 

 shades, take ordinary ceiling lath four feet long, lay them 

 parallel, and two inches or a little less apart, and fasten 

 them in their places by nailing across their ends two 

 strips of boards three inches wide and three feet long. 

 This size of shade is more convenient for handling than 

 larger ones, and being so light are not liable to be broken. 

 These shades laid on the frames will admit air and 

 moisture, and while admitting the direct rays of the sun 

 to every part of the bed during the day, they will not

remain long enough upon any place to cause injury. 

 The constant change of the sun and shade thus secured, 

 is just what is required by delicate seedling coniferse, 

 and some few other kinds of trees, that will be mentioned 

 further on. 



Seeds sown in frames as described are under the con- 

 trol of the cultivator. They can be watered when it is 

 required, more or less shade given if desirable, besides 

 being in a position to be protected in winter, should their 

 hardiness be doubted. Occasionally it may be found 

 necessary to increase the temperature of the seed-bed, or 

 to protect the seed from long continued cold rains. 

 This can be readily done by substituting for the lath, 

 glazed hot-bed sash, that are usually, and should always 

 be found as the ordinary adjuncts of every good garden.
