Sheep Go Four Months without Water. 



Sheep on the Nebo national forest, 

 Utah, go four and a half months with- 

 out water except for such moisture as 

 they get from the dew and the juices of 

 forage plants. 



Grazing sheep on a range entirely 

 destitute of water is due to the increas- 

 ing demand for forage and the efforts 

 of the forest officers to find a place on 

 the forest ranges for all the stock that 



early in the nineteenth century, and 

 was grown from the Selecta Orange. 



As far as can be determined the bud- 

 ded orange trees through which the 

 naval orange wood was introduced in- 

 to the United States were obtained 

 from a plantation by the Rev. F. I. C. 

 Schneider, a Presbyterian missionary, 

 who shipped them to William Saun- 

 ders, then horticulturist, landscape gar- 

 dener, and superintendent of grounds 



THESE SHEEP HAVE NO WATER FOR FOUR MONTHS. 



can safely be admitted. The area on 

 the Nebo which has now proved usable 

 by sheep is high and rocky, a portion 

 of it being above timber line, and it has 

 neither springs nor streams of sufficient 

 size or accessibility to be used for stock 

 watering purposes. The grazing sea- 

 son lasts from June 15 to October 31, 

 and during this period of four and a 

 half months the animals do not get a 

 drink. — U. S. Forest Service. 



The Naval Orange in Brazil. 



A study of the Naval or seedless or- 

 ange in its native home near Bahia, 

 Brazil, has recently been made by 

 plant specialists of the United States 

 Department of Agriculture, and has es- 

 tablished the fact that the variety of 

 the naval orange now so largely grown 

 in this country first came into existence 

 at Cabulla, a suburb of Bahia, Brazil, 



of the U. S. Department of Agriculture. 

 Mr. Saunders grew the trees in the De- 

 partment's greenhouses, and trees pro- 

 pagated from them were distributed to 

 California and Florida. The variety 

 proved to be unsuited to Florida con- 

 ditions but in California it is very pro- 

 ductive and highly valued. Practically 

 the entire present planting of the var- 

 iety in that State can be traced directly 

 back to two of the trees sent there by 

 Mr. Saunders in 1873. — The Agricul- 

 tural Digest. 



The Biological Survey reports that 

 there are thirteen hundred and fifty 

 different species of rodents in North 

 and Central America. Many of these 

 are very destructive. The remedy is 

 to encourage the increase of their nat- 

 ural enemies, the hawks, owls and non 

 venomous serpents.
