Notes on plantations of caprifig- trees, G. Eisex {Pacific Rural Press, 62 {1901), 

 No. 24, />. 'i72). — In Dfder t<i ^;t■(■ll^(■ with certainty .3 crops i>er season of caprifigs, the 

 author advises the planting of several different kinds of eapritigs. The eai>ritig trees 

 should also be grown in at least 2 different plantations as a guard against injury 

 from frost and to insure a (;rop of capritigs when they are wanted. One of the plan- 

 tations should be on low ground out of danger of severe frost. Caprifig trees should 

 be planted close together and at various places about the fig orchard. The trees 

 require no pruning, Tint should l)e headed low and encouraged to sucker- freely in 

 order that there may be plenty of shade for the wasps. Caprifigs should ))e grown 

 on their own roots and not grafted as standards on other fig stock, nor is it ailvisal)le 

 to graft them on the limbs of Smyrna lig trees.

The Butin Schaap method of coffee grafting, A. Prever {Tropenpflanzer, 5 

 {1901), No. 5, pp. 220-224, fig><. '--) and A. Zimmekmaxn {Meded. 'S Lands Plantentuin, 

 1901, No. 49, pp. 54, figs. 32). — The method followed by Mr. Butin Schaap in the 

 grafting of coffee trees is descrit)ed and some notes added as to its practical applica- 

 tion. The method is essentially as follows: The scions are cut out early in the 

 morning and transported in closed baskets to the place of using. Here each scion is 

 cut arrow shape below the first node, and placed in a simple split 3 cm. long, either 

 in the terminal or second bud of the stock. The side leaves are removed, except 2 

 of the smaller uppermost ones of the scion. The graft is tied in place with woolen 

 yarn, l)ut is neither waxed nor smeared over with otlier material. Both scion and 

 wound are then covered over with a glass ])eaker. This preserves a constantly moist 

 atmosphere about the scion and prevents its drying out. As soon as tlie scion and 

 stock have grown together jjoth the glass and yarn are removed. 



Grafting coffee trees is of primary importance in districts where nemiatodes a^e 

 abundant. These severely affect Arabian coffee varieties, but Liberian tree roots are 

 seldom attacked. The Liberian trees are, therefore, used as stock for Arabian and 

 other better sorts of coffee. Another advantage is the increased yields obtained from 

 the Liberian trees when grafted with the Arabian, Maragogipe, or other improved 

 varieties, while the quality of the Araltian coffee, etc., does not seem to l)e in any 

 manner injuriously affected by growing on Liberian stock. It is suggested that this 

 may point the way to the improvement of nonremunerative coffee ])lantations. 



The best trees for stocks are tiiose not less than 3 years old, and the graft is made 

 on the central stem. Older trees that have grown too high may be cut off about 3
