THE CUBA REVIEW

water supply to facilitate the rearing of 

 cattle on the lands not devoted to cane 

 planting. 



A sugar factory with all necessary machin- 

 ery from France will be installed capable of 

 grinding 700 to 800 tons of cane per 24 hours 

 with an extraction of 12% of sugar. 



Later additional machinery will take care 

 of 1,500 to 1,600 tons of cane daily. 



The lands to be acquired will naturally 

 be connected with the Guantanamo and 

 Western Railroad lines and through them 

 with the rest of the island. 



The company will also have its own lines 

 with locomotives, cars, branches and switches 

 sufficient for all needed transportation 

 requirements for sugar and cattle. 



If suitable land cannot be found im- 

 mediately the company purposes to build 

 en a caballeria a factory for the manufacture 

 of sugar, securing its cane from the colonos 

 round about. — La Independeiicia, Santiago

CUBAN FRUIT PRICES 



Arrivals and prices at New York for pine- 

 apples and grapefruit are given by the Fruit- 

 man's Guide as follows: 



Week of May 22. Grapefruit: Receipts 

 light, over 1,200 boxes. Best marks sold at 

 $3.00 to $3.75. Choice from $1.25 to $2.50. 



Light receipts are explained by the state- 

 ment that many crates used for shipping this 

 fruit were stored in the quarantined section 

 of Havana and hence not available. 



Pineapples. Isle of Pines fruit sold at 

 $5.00 per crate for 10s and $3.75 for 12s. 

 The demand was good, $6.00 could have been 

 obtained for 6s or 8s. 



For Cuban 24:S to 36s the price secured at 

 Pittsburgh ranged from $2.15 to $2.40. 42s 

 sold at $1.75. 



Havana pines at New York were of ex- 

 cellent quality. The demand was active with 

 closing range as follows : 



18s, $2.40 to $2.55; 24s, $2.45 to $2.60; 

 30s, $1.90 to $2.05: 36s, $1.55 to $1.70; 42s, 

 $1.40 to $1.50. 



The week's receipts of Havana pines for 

 Maj' 29th, comprised 63,000 crates. The 

 quality of condition of arrivals was veiy good, 

 and demand brisk. The range by sizes was 

 as follows: 18s, $1.75 to $1.80; 24s, $1.85

VALUE OF A COCONUT GROVE 



A coconut grove, properly cared for, yields 

 a sure and steady income. Better culti- 

 vation, the growing of vegetables among 

 the trees the utihzation of seaweed and 

 other manures, yield excellent returns over 

 cost. — Report of the Station of the United

A VALUABLE STUDY 



"Tests of Bond Between Concrete and 

 Steel," b}^ Duff A. Abrams, has just been 

 issued as Bulletin No. 71 by the Engineering 

 Experiment Station of the Universitj' of 

 Illinois. 



In designing structures of reinforced con- 

 crete it is important to know the amount of 

 stress which may be developed between the 

 surface of the reinforcing bars and the sur- 

 rounding concrete before failure is produced 

 by the slipping of the bars. This stress is 

 what is commonly termed "bond." The 

 above-mentioned bulletin gives the results 

 obtained by pulling out bars embedded in 

 blocks of concrete and also the results of 

 tests made to study the bond stresses de- 

 veloped in large reinforced concrete beams. 

 Nearly 2,000 tests are reported and a wide 

 range of conditions are represented. This is 

 one of the most exhaustive studies of the 

 amount and distribution of the bond stress 

 between concrete and steel which has ap- 

 peared .

 gratis upon application to C. R. Richards,

 ment Station, University of Illinois, Urbana,

HOW TO HARDEN CONCRETE FLOORS 



The Chemical Trade Journal of Birmingham, 

 England, recently stated that: "A new 

 hardening miterial for the surface of concrete 

 floors contains 95% of iron dust or iron 

 fl ur. It is added to the dry cement in the 

 proportion of 15 to 25 pounds to each 100 

 pounds and one part of the mixture is used 

 with two parts of sand. This preparation 

 is applied as a top coat to a thickness of 

 Ji> to 1 inch. It forms a hard and durable 

 floor claimed to be waterproof and not 

 slippery and is also used for making new 

 oncrete adhere to old in repau-ing." 



This should be interesti .g information to 

 contractors in Cuba where concrete is so 

 largely used. 



A Boston publication. Fibre and Fabrics, in 

 its issue for May 23d, has the following to 

 say regarding some recent success in growing 

 tree cotton in Cuba. 



"Some of our readers will recall the man 

 who was showing tree cotton gi'own in Cuba 

 at the September convention at the Griswold, 

 New London, in 1912. Many were favorably 

 impressed with the samples, but looked upon 

 the entire scheme as a stock selling enterprise. 

 The promoter has been quietlj- at work since 

 that time and has sold this month his crop 

 of 50 bales at 17 cents a pound. 



"If the claims of the promoters are to be 

 credited, they own sufficient seed to plant 

 what will yield 50,000 bales per year and the 

 quantity can be increased to manj- times this 

 amount with proper financing and manage- 

 ment."
