84 BUIST'S FAMILY KITCHEN GARDENER. 



Strasburg, or Yellow Onion. Large oval, inclining to flat ; 

 very hardy, keeps well and of strong flavor. 



Silver Skinned. White, flat, medium size. Very generally 

 used for pickling. 



Red Dutch. Bark red, medium size, inclining to flat, keeps 

 well, very hardy, extensively grown in the Eastern states for 

 export, strong flavor. 



Portugal^ very large, globular, mild flavor ; does not keep

 other varieties : such as Globe, James's Keeping, Tripoli, Read-

 heavy crops. I have seen instances of twenty-two successive
