mentioned that Herr Mulder, in Sudimara, (West Java) obtained in 

 in 1897 from three trees 105*6 lbs. and twenty months later from the 

 same trees 99 lbs. This is, respectively, per tree 35J lbs. and 33 lbs. 



YIELD OF "RUBBER IN MEXICO. 



R. P. Probasco, of Chicago, fsivours The India Rubber World witk 

 the results of tapping cultivated Castilloa rubber trees by A. B. 

 Coate, superintendent of La Soledad Plantation, on Trinidad River, 

 Isthmus of Tehuantepec. Mr. Hrobasco received four specimens — 



1. Weight, 3 lb. 2 oz. ; collected from three trees, in diameter 16, 12£ and 



14 inches. 



2. Weight, 1 lb. 2 oz. ; yield of one tree, 12 inches in diameter. 



3. Weight, 1 lb. 9 oz. ; yield of one tree, 11£ inches in diameter. 



4. Weight, 2 lb. 4 oz. ; yield of one tree, 18 inches in diameter. 



Total weight, 8 lb. 1 oz., yield of six trees, gives an average of 1 lb. 

 5J oz. per tree. None of the trees is over eight years; some of them 

 only six. Rain fell while the trees were being cut, washing away 

 some of the rubber milk, and various other unfavourable conditions 

 existed. — {Queensland Agricultural Journal.) 



THE ALMOND BAG WORM. 



A correspondent has sent specimens of the Almond Bag Worm 

 attacking the Orange tree. No record has been made of its having 

 been found before on the orange. 



There is a note in the Journal of the Institute of Jamaica for 

 August, 1893, on this insects It quotes from Mr. Bowrey's Report 

 as Curator for year 1879-80 : 



" The curious ' case' caterpillar, of which T have secured a specimen 

 of the male moth which is winged, and also of the female which is 

 apterous and never leaves the ' case' formed by the larva. This is the 

 caterpillar which was noted on almond trees shortly after the August 

 hurricane This is its ordinary food plant, and I can only account for 

 its being specially noted in August last by supposing that the trees 

 on which it feeds being blown down it was brought under popular 

 notice. For years I have seen it on almonds, and I doubt if it has 

 been as plentiful this year as it usually is. Its ' case' so exactly re- 

 sembles in colour and texture the small branches of the almond as to 

 pass unnoticed except special attention be called to it." 



Prof. C. H. T. Townsend proceeds as follows, and then gives an 

 exact description of the insect, probably Oiketicus abbottii Grote : 



" A large number of these small bag-worms were found on an 

 almond tree in the Marine Gardens, in Kingston, on June 24, 1893. 

 Individuals of all sizes occurred, from tiny to large and evidently 

 fully grown ones. The largest ones were found attached very strongly 

 to the under side of the branches in places, where they were with 

 great difficulty detached owing to the great strength of their silk. 

 The smaller growing ones were found on the leaves, clinging to the 

 underside of the latter in which they eat irregularly round holes, 

 which they gradually enlarge. This gives the foliage the appearance 

 of having been raked and riddled with shot of various sizes."
