that must not be planted in the open until there is no 

 danger of frost. 



CUCURBITOUS OR VINE CROPS (Group 9) are "tender" 

 vegetables that require high temperatures and usually a 

 long season, Sandy loams preferred. 



CORN, OKRA AND MARTYNIA. (Group 10.) High temper- 

 atures are necessary for the best results. The soil should 

 be moist and fertile. 



PERENNIAL VEGETABLES. The soil should be enriched 

 annually by the application of rotten manure. Nitrog- 

 enous fertilizers are especially beneficial. 



Although the foregoing method of classification is ex- 

 ceedingly valuable, the requirements of crops, even in 

 the same group, are so variable that a complete discus- 

 sion of each crop is necessary to give accurate cultural 

 directions. The vegetables are taken up in alphabetical 

 order, because this arrangement makes the book most 

 convenient for reference.
