8 INTRODUCTOKY. 



that there were at the end of 1916 approximately 591,000 silos in 

 the United States. Wisconsin alone had 55,992 silop at the end of 

 1915, one county having 2,772 and the Wisconsin total at the end of 

 1916 probably exceeded 62,000 sUos. This means an average of five 

 silos for every fourteen farms in the state. Counting the average 

 silo 14x28 feet, the contents would amount to 5,146,000 tons. On 

 Jan. 1, 1916, the New England states had 25,756 silos, or one to 

 every seven farms. New York, Pennsylvania, New Jersey, Dela- 

 ware, Maryland, and West Virginia had 81,741 silos, or one to 

 almost e'ight farms. The Southeastern states east, of the Missis- 

 sippi had about 19,000 silos, or one to every 88 farms. In this sec- 

 tion Kentucky, Tennessee, Virginia and North Carolina are par- 

 . ticularly active in silo building. The central states of Ohio, 

 Michigan, Indiana, Illinois, Wisconsin, Iowa, Missouri, Kansas and 

 Nebraska showed 198,115 silos, one to every 9.8 farms. 38,172 silos 

 were credited to the southwestern states, one to each 15 farms, and . 

 nearly the same ratio was shown for the states of Minnesota, the 

 Dakotas, Montana and Idaho, with 25,630 silos. Not only has the 

 use of silos spread to every section of the United States, but the 

 corn belt has been pushed steadily northward with the result that 

 the building of silos is making headway in Manitoba, Saskatche- 

 wan, British Columbia and the Canadian northwest generally. 

 During the past two years there has been a wonderful increase in 

 the interest taken in the subject, an interest fostered by the ex- 

 ample set by the Canadian Government Experimental Farms and 

 the literature available from them. In eastern Ontario official 

 figures show that 1,258 new silos were built during 1915, and the 

 total for the Province for that year alone probably exceeded 2,500 

 sllos. 



The use of the silo has spread through all parts of the world. 

 Hundreds, even thousands, are In use in Australia, New Zealand, 

 South Africa, India, South America, Spain, Norway, Sweden, and 

 in other parts of Europe. In England the interest in silos has 

 been increasing rapidly, some forty modern silos having been 

 erected in East Anglia alone during the past two years. Bamboo 

 silos are used in Japan. Concrete is very popular In many parts 

 of the world. There are thirty-flve or forty silos in the five prin- 

 cipal Islands comprising the Hawaiian group, despite the fact that 

 dairying there relies largely upon Its forage in the form of soiling 

 crops, which can be grown the year round. In these and various
