We had marked Dr. Lindley's article, when we first re- 

 ceived it, for insertion in our Magazine, intending to offer 

 some remarks thereon. But the crowded state of our pages 

 has prevented us from yet finding an opportunity to insert it. 

 We hope, however, to do so soon, and in the mean time we 

 commend the remarks of Mr. Ernst, to the attention of our

Art. III. Guano : its use and application. By Charles 

 Robinson, Esq., New Haven, Conn. 



With us, much injury was done to gardens last season, by 

 the use of this most powerful manure. For this result there 

 were three obvious reasons, either of which alone would have 

 been sufficient. 



First. — It was applied too freely. From a vast number of 

 experiments carefully made in England, it is found that three

 thoroughly tilled, the quantity may be greatly increased. In-

 previously worked into the soil. Two pounds, therefore, to 

 the square rod, or one ounce to the square yard, is a full 

 allowance on ordinary soils. 



With us it has been tried generally as an experiment, and

In the April number of the Monthly Journal of Ag?'iculfure, 

 I notice that " Alexander Jones, Esq., used eight pounds with 

 half a bushel of ashes, on a patch of tobacco plants, ten feet 

 by sixteen. It killed them outright ;" and so it ought to have
