man may work hard for six or eight rods in a day 

 of twelve hours. Trenching, if only one spade deep, 

 without the crumbs or shovelling at bottom, a man will 

 dig almost as much as by plain digging ; or two spades' 

 depth, from four to six rods a day may be good work, 

 though in harsh-working ground digging three or four 

 rods per day may be hard work. (Mawe.) Most garden 

 soils dig best the day after a fall of rain ; and if the soil 

 has in its composition a larger proportion than usual of 

 clay, the operation will be facilitated by dipping occa- 

 sionally the spade into water. Most gardeners object 

 to digging while snow is upon the ground, and the ob- 

 jection is not mere prejudice, for experience proves the 

 bad result of the practice. The evil is owing to the 

 great quantity of heat required to reduce ice or snow 

 from the solid to the fluid state ; and when buried so 

 that the atmospheric heat cannot act directly upon it, 

 the thawing must be very slowly effected, by the ab- 

 straction of heat from the soil by which the frozen mass 

 is surrounded. Instances have occurred of frozen soil 

 not being completely thawed at midsummer. 



DIGITALIS. Foxglove. (From the Latin digitale, a 

 finger-stall ; referring to the shape of the flowers. Nat. 

 ord Figworts [Scrophulariaceae]. Linn. n-Didynamia, 

 2- A ngiospermia.) 



The seeds should be sown ha the autumn ; when sown 

 in the spring they often remain twelve months before 

 they sprout. Division ; and most of them plentifully 

 by seeds ; common soil.

 the opening of the flower. Nat. ord. Bloodroots [Haemo- 

 doraceae]. Linn. $-Triandria t i-Monogynia. Allied to 

 Anigozanthos.) 



Greenhouse herbaceous plants, with sword-shaped 

 leaves, from the Cape of Good Hope. Divisions, when 

 fresh growth is commencing ; seeds in a slight hotbed, 

 in March or April ; sandy loam and peat. Summer temp., 

 55 to 75 ; winter, 40 to 45.

DILL. (Ane'thum grave'olens.) Its leaves and umbels 

 are used in pickling, and the former in soups and sauces. 



Soil. It may be cultivated in any open situation ; 

 but if for seed, a sheltered place, and rather dry soil is 

 better. 



Sowing. Sow immediately the seed is ripe, for if kept 

 out of the ground until the spring it often is incapable 

 of germinating. If neglected until the spring, sow from 

 the close of February until the commencement of May. 

 Sow in drills a foot apart, the plants to remain where 

 sown. When of three or four weeks' growth thin them 

 to about ten inches apart. The leaves are fit for gather- 

 ing as wanted, and the umbels about July and August. 

 In September their seed ripens, when it must be imme- 

 diately cut, and spread on a cloth to dry. being very 

 apt to be shed.
