be selected and some care be given to its planting and first growth. 

 Wild seedlings of the proper size, and in sufficient quantity, are always 

 hard to find; it is much better to sow, in a nursery, the seeds of the 

 shrubs selected and raise our own seedlings, which we then can trans- 

 plant at the most opportune time- This nursery ought to be made in 

 well prepared and manured ground, and freely watered. The following 

 year, the young stems can be transplanted, wherever needed, at the 

 beginning of or during the rainy season ; that is, in September in West- 

 ern Texas, ami later east of San Antonio. Transplantation done in the 

 dry season, or without the prospect of several heavy rains to start the 

 plant, would be futile. 



Mezquit, as a hedge plant, deserves particular attention. I believe 

 it ofl'ers the best chances of success on plains and high prairies. 'Next 

 in value, in the same situation, I would recommend Zizyphus ohtusifolms 

 and the several species of Condalia. The other native shrubs capable 

 of making good hedges are: Celtis pallida, Gastela Nicholsoni, Koeherli- 

 nia spinosa, Prosopis pubescens, Acacia Greggii, A. Berlandieri, A. amen- 

 tacea, A. Wrightii, A. Rcemeriana, A. Farnesiana, Mimosa biuncifera, 

 Ceanothus Fendleri, They have all been already noticed.
