 nitrogen. so«linm. and i-hiorin. and a low percentage of phosithoric acid and

 reducing sugars, and very high in nitrogen content.

 {Ann. R/it. liiir. Siif/dr bliiit. Std.s. [Qiiccnshnitl ]. I'.XH, pii. 'f(i). — A brief state- 

 ment for 1!»(»T of the work of the sugar experimental station at Mackay, of two 

 substations in sugar districts, and of the laboratories, together with an account 

 of the economic and financial conditions of the sugar Industry in Queensland, 

 Is present tHl. 



The results show that the varieties New (iuinea SA, 15 or Hadila. 24 or (Joru, 

 24A, and 24H still maintain the lead in sugar production. The first rattoon 

 cro|) uf the 10 best varieties grown with and without irrigation and with and 

 without manures show that the average of the irrigated and nonirrigated 

 plats with manures gave an increase of !».3 and 10.7 tons of cane per acre, 

 respectively. ap])arently due to the fertilizer applied. The largest increase 

 due to manure was on the nonirrigated i)lats of New Guinea 24B, the increase 

 being 15.4 tons per acre. The smallest difference in yield occurred on the non- 

 irrigated plats of Bois Rouge, the increase on the manured plat being only 5 

 tons greater per acre than on the plat receiving no manure. 



Deep su!»soiliug between the rows, with subsequent cultivation of the rat- 

 toons, increased the yield by 11.9 tons of cane and 1.7 tons of sugar per acre. 

 In this ex|)eriment the jilats were neither manured nor irrigated. 



The outcome of distance experiments indicates that 1 plant with ,3 eyes, with 

 <» in. between the plants in the row, is the best way of planting seed in the 

 row. .\ny increase exceeding 5 ft. between the rows is likely to result in a 

 lower weight of cane and yield of sugar per acre, while less than 5 ft. between 

 the rows can result in an increase of cane and sugar. 



Kxiteriments with new varieties have brought out the fact that the best sorts 

 are dclicifut in arrowing. A descriptifni of the introduced canes is given. 



The stripping of sugar cane in Formosa, T. Mi'kakami ( Intcnidt. fiiifjar 

 ■fiiiir., II) ( i;i(is), Ao. //,s, pp. '/7.S-'/(S.'/). — Results of i'Xiieriments in tlu' strii»ping 

 of sugar cane in Formo.sji indicate th.it this method of treatment for imiiorted 

 <'anes c.iuses a decreas«* in sucrose together with a lowering of the purity 

 • oetllcient. while at the sjinie lime the gIu<'ose and fiber are increased. This the 

 author inter|irets as due to .i (•heniical activity by which the non.sucros<» is 

 transfonnfil into sucro.se .-ind sucrose into glucose. This chemical .Mctivity 

 may be intluenced by the presence of a large nmoimt of s.ill Mbsorhcd with the 

 water. The fresh food materi.al thus obtained is c.\pcn(le«l in the growth of 

 ail canes except the coIohmI canes.
