GOING UP A GRADE 



In transplanting all small seedlings, they are 

 placed in straight rows in the boxes ; usually eight 

 rows with eight plants in a row in the eighteen- 

 inch boxes; but, for larger individuals, six rows 

 of six plants; or, on the other hand, ten rows of 

 ten or even twelve rows of twelve in case of the 

 smallest ones. 



After standing in the greenhouse for a week 

 or two, the boxes of seedlings are removed, 

 usually to a sheltered place out-of-doors, in order 

 that they may continue growth and become hard- 

 ened through exposure to sunshine and outdoor 

 air. Later, they may be safely transplanted into 

 other boxes, giving them more room for growth, 

 or to the field where they may be planted in long 

 rows about four feet apart, so that they may after- 

 ward be cultivated by horsepower or tractor in 

 the usual way. 



In general the treatment here described is em- 

 ployed for cactus, berries, lilies, begonias, grasses, 

 potatoes, roses, ferns, or any of the thousands of 

 species of domestic, foreign, arctic, or tropic seeds 

 which are received from collectors. 



In transplanting, it is best to have the boxes 

 of plants carried into the field, and with most 

 plants it is best to saturate the soil in the boxes,
