ENCYCLOPEDIA OF PRACTICAL HORTICULTURE 



rosette in Utah is from the effects of 

 these saline waters. Sometimes it is found 

 on the bench lands where there is seep- 

 age from the mountains. I found a few 

 rosetted trees with galled roots, gopher 

 and aphis injuries where there seemed 

 to be no rise and fall of the water table 

 and no seepage from the mountains, but 

 by far the larger part of damage was 

 evidently caused from water. 



NeTada 



I did not visit Nevada, but from in- 

 formation that is undoubtedly reliable, 

 the conditions are similar to those of 

 Utah. There the agricultural and hor- 

 ticultural regions are surrounded by 

 mountains that drain into lake basins like 

 Pyramid Lake, Carson Lake and Walker 

 Lake, that have no outlets and the water 

 rises and falls with similar results to 

 those of Utah. 



Grand Junction, Colorado 



At Grand Junction rosette is common 

 and the worst rosetted trees are on the 

 low lands where the water is heavily 

 charged with alkali. Their problem of 

 drainage will become serious with the 

 irrigation of their higher lands. 



Crossing the Great Divide at Tennessee 

 Pass, I came into the Arkansas valley. 

 In this valley the great orchard sections 

 are near Canyon City. Here we found 

 the same causes and the same ef- 

 fects as on the west side and were re- 

 minded again of the "Unity and Univer- 

 sality of Law," and that everywhere sim- 

 ilar causes produce similar effects. 



I have found rosette on high lands and 

 low lands; on soggy soil and dry soil; on 

 shallow soil and deep soil; on gravelly 

 soil and the finer volcanic ash; at Brem- 

 erton, on Puget Sound, and in Texas, near 

 the Gulf; in Washington, Oregon, Cali- 

 fornia, Montana, Utah, Colorado, Kansas, 

 and Oklahoma. I have authority for say- 

 ing that it is found in West Virginia, the 

 Carolinas, and in Europe. Of course in 

 the humid regions it grows under differ- 

 ent conditions and is not so prevalent. 

 Some of the conditions that produce it 

 are not present in the soils of the humid 

 regions, but some of them are. and the 

 reason it has not been largely observed 



is because we have not trained ourselves 

 to observe it. In fact, it existed in the 

 orchards of the Pacific coast states years 

 ago, but it has only been noted within 

 the last two or three years. 



Rossette Anywhere 



Anywhere rosette might exist under the 

 following conditions, viz.: 



1. Where there is good soil and plenty 

 of plant food, but where the organs for 

 the assimilation of food are injured. 



2. Where there is too much water and 

 the oxygen is excluded from the roots. 



3. Where there is not enough water, 

 and plant food is not available. 



4. Where there is too much alkali, and 

 the root hairs are destroyed. 



5. Where there is hard pan and as a 

 consequence the roots are malformed, so 

 that there is not a proper circulation, nor 

 suflBcient plant food available. 



6. Where the roots are injured by clean 

 cultivation. 



7. Where gophers or other rodents in- 

 jure the roots. 



8. Where aphids, eel worms or other 

 insects injure the roots. 



9. Where the trees are set in a scab 

 soil that contains but little plant food. 



10. Where land is puddled by irrigation, 

 excluding the air and smothering the 

 root hairs. 



11. Where the water contains mineral 

 elements that destroy the root hairs. 



There are other conditions under which 

 it might exist, but to sum it all up, the 

 roots are the feeding organs and in pro- 

 portion as these organs are injured, in 

 that proportion the supply of food is cut 

 off, and injury must result that would 

 become manifest in the top. 



I conclude, therefore, that the claims of 

 those who seem to be in conflict as to the 

 causes, are all of them right; for I think 

 I have verified most of them. That is, 

 they are right in what they affirm, and 

 are in danger of being wrong in what 

 they deny. 



Tlie Cure of Rosette 



The cure of rosette is not the same in 

 every case. 



While it is true that we must strive to
