production of silk. Mallee could be prepared, it is estimated, at a 

 cost of £9, 10s. per acre to grow a crop of such trees. And as the 

 mulberry comes into profitable use for silkworm feeding in four or 

 five years after planting, giving a net profit derived from the silk of 

 2s. for each well-developed tree, a profit of £850 could be derived 

 from fifty acres so planted. We have already noticed the vigorous 

 inauguration of wattle culture for tanning purposes by Mr. Brown. 

 But some of the facts as to the yield of tannin may interest home 

 users. Thus the broad - leafed wattle. Acacia _/92/c?ia7i^7i(X, gave 

 results similar to those obtained by Baron Mueller, who obtained 

 from it when artificially dried 30 to 45 per cent, of tanning matter. 

 The percentage of tannin does not diminish with age in healthy 

 trees, though tree sickness at any stage of growth at once affects the 

 yield. The bark upon the branches and twigs of this acacia was 

 also found to contain a very high percentage of tannic acid.

 trations. London: All booksellers. 1885. 



Heee is a novelty in guide-books. The shape is oblong, adapted 

 like a surveyor's field-book for the side pocket. Besides a handy 

 map, full-sized illustrations of forest scenes adorn almost every 

 second page, all reproduced from nature, and from photographs taken 

 by the London Stereoscopic Company, and these are supplemented 

 by smaller companion woodcuts. The Walks are written by the 

 chief local authorities on this district of a manifold literature, and 

 comprise cycling routes, and plain instructions for pedestrians, as 

 well as the latest facts on the geology, archasology, and biology of 

 the forest. Best of all, the ornamental cover of this booklet Avould 

 befit any drawing-room table, whilst the price is sixpence !
