INSECT PESTS OF OHIO SHADE AND FOREST TREES 185 



in other words, about a dollar per tree annually, including all items, 

 such as new plantings, spraying, trimming, protecting, cultivating, 

 watering, etc. At the same time more than $10,000 of the sum 

 named was expended for permanent improvements in parks, for 

 maintenance of comfort stations, and for other items closely asso- 

 ciated. 



TREE DOCTORS, QUACKS, ETC. 



Today when we are almost without laws regulating the prac- 

 tice of tree surgery, public spraying and the like, the public is at 

 the mercy of the practitioner. Calling himself an expert and using 

 a few high-sounding terms with which his glib tongue paints a 

 masterpiece of the woe and destruction sure to ensue if his services 

 are not accepted forthwith, he holds the average householder at his 

 mercy. The so-called expert can charge any price per hour and 

 work as many hours as he cares and the householder pays the bill. 

 The highly-groomed trees sometimes seen aptly remind one of the 

 equally over-groomed town dandy. Moreover, it is likely that the 

 pampering, particularly the practice of removing all the rough bark 

 from the trunk, is equally as unprofitable as the time spent by the 

 dude in primping. Further, the removing of the rough bark may 

 cause positive harm to the tree. 



Still another class of tree practitioners abound who promote 

 and apply the use of fake remedies, as, for example, the man who 

 sells a concoction that he says is effective against all forms and 

 types of insect pests. Like cure-all patent medicines such nostrums 

 and their promoters should be avoided. 



From the foregoing remarks, however, the writer does not 

 wish to imply that all present-day tree surgeons are bad, nor to 

 reflect in the least upon the work of the reliable ones, for he has 

 come in close contact with some men who were performing high- 

 grade, conscientious service. Such legislation as that proposed, 

 tending to limit the practice of their profession, would prove a boon 

 rather than a hardship to such men. 



SPRAYING MACHINERY AND ACCESSORIES 



Tremendous progress in the development of spraying ma- 

 chinery has been made, particularly during the last decade. One of 

 the more important phases of this outgrowth has been the produc- 

 tion of special types to serve the requirements of different classes 

 of work to be done ; this has not only resulted in increased efficiency 

 in the use intended but at the same time has made necessary the
