[N. S. Vol. I. No. 25. 



Mr. Buckhout after ' five years' experience 

 in planting forest trees ' concludes in the 

 Pennsylvania Station Report " that consider- 

 ing the time, expense and work involved, 

 artificial forest planting cannot be recom- 

 mended, at least in the way pursued in the 

 experiment and that natural methods of re- 

 foresting supplemented by some seed sow- 

 ing, thinning and planting will suffice for 

 the present." Mr. McCarthy, of the ISTorth 

 Carolina Station, has prepared a bulletin 

 upon seed testing and fully describes its 

 uses and methods. Weeds receive atten- 

 tion from Mr. Wooton, of the ISTew Mexico 

 Station, who figures several of the worst in 

 his Territory. 



Under diseases of plants some grape 

 troubles in New York are reported upon by 

 Mr. Lodeman of Cornell. Thus the so-called 

 ' shelling ' is ascribed to one or more of four 

 causes, namely, parasites, conditions of 

 vine, of soil, or of atmosphere. An English 

 experimenter shows that finely ground lime 

 700 pounds per acre will check the club 

 root in turnips. Eesin is found by Mr. 

 Webber to be effective in preventing the 

 soot}' mould of the orange. 



Economic entomology receives considera- 

 tion under many heads as the damage 

 caused by American locusts, chinch bugs, 

 codling moth, etc. A new saw-flj' and pear 

 insect are mentioned and many species are 

 named under beneficial insects. Gas treat- 

 ment for destroying scale insects is reported 

 upon from California and ' Entomology and 

 Quarantine ' is considered. 



Much space is given to the consideration 

 of foodstuffs, their analyses, digestibility, 

 etc., the Maine Station perhaps taking the 

 lead in these matters in the copj' of the 

 Record in hand, while Utah and Minnesota 

 come in for a share in ' dairy herd records ' 

 and ' relative value of corn and oats for 

 horses.' Several papers are mentioned by 

 title or at length under dairying. 



Surely enough has been here given to 



show that the Experiment Stations of the 

 United States are pushing on along manj^ 

 lines, and that through the facts accumu- 

 lated principles cannot but be laid bare. 



THE HORTICULTURALISTS' RULE-BOOK. 



The first edition of this ' comj)endium of 

 useful information for fruit-growers, truck- 

 growers, florists and others ' by Professor 

 L. H. Bailey, of Cornell Universitj-, was 

 published in 1889 and a second in 1892. 

 The great advances made in methods of 

 combating insect and fungous enemies dur- 

 ing the past few years led the author to re- 

 vise and extend his work. A chapter upon 

 greenhouse heating has been added and 

 another upon the current literature of hor- 

 ticulture. 



The following are some of the leading 

 subjects considered : insecticides and in- 

 jurious insects, plant diseases with preven- 

 tives and remedies; injuries from mice, 

 rabbits and other animals ; weeds, seed- 

 tables, etc. There is a chapter upon Rules 

 in which are given rules for naming fruit, 

 codes of various societies, etc. Within the 

 flexible covers of this little book the pub- 

 lishers (Macmillan «& Co.) have neatlj^ 

 packed together a surprising amount of 

 valuable information. Here the horticul- 

 turist may learn how much seed to sow per 

 acre, how many plants to set in his orchard, 

 how to keep ofi" the enemies to his crop, 

 and when to harvest and market it. Not 

 the least is a list of the leading books that 

 have been published upon horticultural sub- 

 jects and within easj' reach of crop grow- 

 ers. Byron D. Halsted.
