be potted o£f when very small, and kept growing in pots 

 until wanted for permanent setting in the orchard, as 

 the plants in open ground do not transplant well. Routed 

 cuttings, of course, should be treated the same as seed- 

 ling plants as to final handling. 



Guavas grow well on any soil, sandy or clayey, rich 

 or poor, dry or moist; but they will not live in a bog. 

 On too rich soil the growth is apt to be rank and the 

 quality of the fruit injured. This fruit tree is as easily 

 grown under sheds as is the pine-apple in Florida, and 

 when thus protected is certain to bear abundantly, even 

 well out of the tropics. e. N. Reasoner.

 ragdcece. The little family Haloragacess comprises 

 about 100 widely scattered and heterogeneous species in 

 9 genera. In the northeastern states are the aquatic 

 genera Callitri''lu-, rro^.-rpinnca, Hippuris, Myriophyl-

 jointed distributions, ("iuiinera has perhaps a dozen 

 known species in S. Afr., Abyssinia, Java, Tasmania, 

 Hawaii and S. Amer. In general appearance the Guu- 

 neras are wholly unlike our native haloragaceous plants. 

 The lvs. are gigantic and more or less orbicular, radi- 

 cal : fls. perfect or imperfect, small, packed in a great 

 cob-like spike ; petals 2 or none ; calyx none, or with 

 2-3 lobes ; stamens 1 or 2 : ovary 1-loculed, bearing 2

 and with protection the two following species may be 

 grown even in some of our northern states.
