stem which stands betwixt the cotyledons and the true leaves, 

 whilst the hvpocotyl, or that portion of the stem below the cotyledons 

 is obsolete. In II, however, — the Burpee — the stem portion is very 

 short, and the root portion is long and is partly comprised of the 

 hypocotyl, which, by elongating, elevates the seed halves into the 

 air. If, now, the outer covering or skin is removed, and the bean 

 is placed on its back, we see the parts as shown in the lower 

 diagram. Here, again, only one-half of the bean is shown. These 

 views emphasize the long radicle of the Burpee (on the left) and 

 the very short radicle of the Barteldes (on the right).

I have finally arrived at the point of saying something about the 

 economic value of these dwarf Lima beans. I am convinced that 

 these beans, as a class, are very valuable. Their great merit is 

 earliness. They are from two weeks to a month earlier than the 

 tall varieties from which they came. Their productiveness has 

 not been reduced in proportion to the reduction in size of the 

 plants, so that I believe that it is possible, in the north to secure 

 greater total yield per acre from the dwarfs than from the pole 

 varieties, seeing that the plants require less room. They are also 

 much cheaper to grow. They require no poles. In central New 

 York, the tall Lima beans are always a precarious crop, on account 

 of their lateness and the liability of being injured by midsummer 

 droughts at the time when the pods are setting. The earliest 

 varieties of these dwarf Limas are those which are derived from the 

 Sieva type, as Henderson and Jackson. The following field notes 

 of the varieties indicate our experience with them : *
