The destruction of the red cedar has been quite univer-sally recommended as the best and most practical method ofcontrolling apple rust. Although this method of control isso generally accepted we find only one reference to a carefulexperiment for determining its efficiency. Jones (1893, p. 83)as quoted on page 6, secured some definite evidence regard-ing this point. Reed (1914, p. 23) gives reports from orchard men as tothe effectiveness of cutting out cedars, but details as to dis-tances, area, etc. are not mentioned. The value of the cedars must be taken into considerationwhen dealing with a problem of this kind. The red cedar,Juniperus virginianae is of very little commercial importancein West Virginia. It occurs quitecommonly throughout thestate and is abundant in some of the principal apple growingsections. Most of the growth is of no value because of itsinferior, bushy development. There are many fields which

(Plate IX, fig. 3.)The larger trees find use as fence posts and telephone poles,but comparatively few are valuable for sawed lumber, and itis said that only the red, heart wood is good for fence posts.The sentimental value which may be attached to cedars isoften a factor of great importance, and is far more difficult todeal with than a mere commercial value. There are very fewplaces where the value of an orchard would not greatly out-weigh the value of all the red cedar trees to be found withinsuch range that they would be likely to produce serious rustinfection. The very destructive apple rust infection of 1912 broughtthis disease to a conspicuous place in the list of apple enemies,and during the year 1913 the State Crop Pest Commissiontook action in regard to the destruction of red cedars in cer-tain sections of West Virginia.
