Olive Culture and Oil Manufacture in the Arid Southwest. 
University of Arizona Agrl. Exper. Sta. Bui. 62 . 
This is a suggestive bulletin on the history and cultivation of 
olives in Arizona. It discusses the propagation, draining, culture, 
the enemies, yields and products of the olive orchard. It gives also 
a number of experiments which were undertaken for the purpose of 
getting fundamental facts in the manufacture of olive oil, and con¬ 
cludes that many olives as grown in Arizona are well adapted to oil 
making. It shows that the Arizona olive is not below the California 
product in recoverable oil content. 
New Methods of Plant Breeding. Bureau of Plant Industry, 
Bulletin 167 . 
The improvement of plants by cross-breeding varieties is gradually 
becoming an important factor in the culture of many of our field and 
garden crops. The Plant Propagator of the Bureau in this bulletin 
gives the methods he has used to accomplish what have been hereto¬ 
fore considered impossible or difficult crosses. Owing to the minute¬ 
ness and delicacy of the floral organs of numerous plants emascula¬ 
tion is impracticable, but by the new process of “depollination” 
undesirable pollen may be removed from the stigma before fecunda¬ 
tion takes place, by the application of water or compressed air to the 
stamens. The method is described, together with the tools required 
and the devices used. The writer shows how this new method of 
preparing flowers for crossing can be applied to a wide range of sub¬ 
jects. Information on the latest investigations in cross-breeding is 
given. 
Analyses and Valuations of Commercial Fertilizers and 
Ground Bone. The Cost of Available Nitrogen, N. J. Agrl. 
Exper. Stations, Bulletin 224 . 
The balance of the- analyses of the fertilizer inspection for 1900 ’ 
a portion of which was reported in Bulletin 223 , is given in this bulle¬ 
tin, together with a discussion of the whole inspection. A schedule 
of trade values of the essential elements of plant food is given and an 
examination and valuation of manufactured brands, giving their 
guaranteed and actual composition, the Station’s estimate of valua¬ 
tion and the selling price, together with a comparison of the value of 
plant food guaranteed and the Value of the amount delivered. 
In the purchase of fertilizers not only the quantities of the con¬ 
stituents present in the brands, but their percentages of available 
plant food is to be considered, and in this connection the utilization 
of nitrogen is the important consideration. There is, however, no 
strict relationship between commercial and agricultural values of the 
various nitrogenous materials, and the bulletin demonstrates that 
the cost to the farmer of any one form is measured not by its useful¬ 
ness to him, but by the cost in the market. 
Crown Rot, Arsenical Poisoning and Winter-Injury. N. Y. 
Agrl. Exper. Station, Geneva, N. Y., Technical Bulletin No. 12 . 
The New York Experiment Station at Geneva has investigated 
this subject of crown rot, which has been so frequently attributed to 
low temperatures, fungous enemies, and bacterial organisms. The 
author of this bulletin is inclined to believe that the main cause of 
crown rot is low temperature, and that this is closely related to in¬ 
fluence of soil and soil moisture, and possibly to the question of stock 
and scion relations. The bulletin gives a very exhaustive survey of 
the subject ,but offers little in the way of suggestions for prevention 
or treatment. 
Lime Sulphur Washes. The New York Experiment Station has 
issued as Bulletins 319 and 320 a discussion of the chemistry of lime 
sulphur, and a comparison of the concentrated forms of the lime 
sulphur mixtures as found in the different methods of manufacture. 
Both of these bulletins are important, but the latter is one which an 
orchardist can use in his business to decided advantage.
