tard-tree of Scripture^, which here attains a height of 

 forty feet), Ixoras, and the numerous family of Cassias. 



Lastly, after a sufficiency of earth has been formed by 

 the decay of frequent successions of their less important 

 predecessors, the ground becomes covered by trees of 

 ampler magnitude, most of which are found upon the 

 adjacent shores of the mainland — the Margoza^ fi^om 

 whose seed the natives express a valuable oil ; the 

 Timbiri ^, mth the glutinous nuts with which the fisher- 

 men " bark " their nets ; the Cashu-nut ^ ; the Palu ^, one 

 of the most valuable timber trees of the Northern Pro- 

 vinces ; and the Wood-apple ^, whose fruit is regarded 

 by the Singhalese as a specific for dysentery. 



But the most important fact connected \vith these 

 recently formed portions of land, is then- extraordinary 

 suitabihty for the growth of the coco-nut, wliich re- 

 quires the sea-ak (and in Ceylon at least appears never 

 to attain its fidl luxuriance when removed to any con- 

 siderable distance from it)^, and which, at the same time, 



^ The identification of this ti-ee 

 with the mustard-tree alluded to by 

 our Sa^dour is an interesting fact. 

 The Greek term aiva-mc, which occurs 

 Matt. xiii. 31, and elsewhere, is the 

 name given to mustard; for which 

 the Arabic equivalent is charclul or 

 khardal, and the Sp'iac hhardalo. 

 Tlie same name is applied at the 

 present day to a ti-ee which gi-ows 

 freely in the neighbourhood of Jeru- 

 salem, and generally tliroughout 

 Palestine ; the seeds of which have 

 an aromatic pungency, which enables 

 them to be used instead of the ordi- 

 nary mustard (Situipis niyra) ; be- 

 sides which, its structure presents all 

 the essentials to sustain the illus- 

 tration sought to be established in 

 the parable, some of which are want- 

 ing or dubious in the common plant. 

 It has a veiy small seed ; it may be 

 sown in a garden : it gTows into an 

 " herb," and eventually " becometh 

 a tree ; so that the birds of the air 

 come and lodge in the branches there- 

 of." "With every allowance for tlie 



extremest development attainable by 

 cidture, it must be felt that the di- 

 mensions of the domestic sinajns 

 scarcely j ustify the last illusti-ation ; 

 besides which it is an annual, and 

 caimot possibly be classed as a " tree." 

 The khardal gTOws abundantly in 

 SjTia : it was found in Egj^jt by Sir 

 Gardner Wilkinson ; in Arabia by 

 Bove ; on the Indus by Sir Alex- 

 ander Bm-nes ; and throughout the 

 north-west of India it bears the 

 name of kharjal. Combining all 

 these facts, Dr. Royle, in an erudite 

 paper, has sho^ai demonstrative 

 reasons for believing that the Sal- 

 vadora Persica, the " kharjal " of Hin- 

 dostan, is the "khardal" of Arabia, 

 the " chardid " of the Talmud, and 

 the "mustard-tree " of the parable.
